    AT&T Asks FCC to Block T-Mobile From Expanding Network With SpaceX Satellites

    AT&T is trying to block T-Mobile’s plan to use SpaceX’s Starlink satellite network to expand its mobile service.

    The Federal Communications Commission asked for public comment on T-Mobile’s SpaceX plan last month. AT&T and its affiliates filed a complaint Thursday, asking the agency to stop the plan and saying it could “jeopardize or inhibit” its wireless and mobile broadband services.

    AT&T has spectrum rights adjacent to the range that SpaceX would be using for this plan, which would require the latter to modify its license for its network of orbiting satellites to receive and broadcast signal to and from mobile devices. SpaceX would use the so-called PCS G-Block of signal bands that are between the 1.9GHz and 2GHz range, according to Ars Technica, which reported the story earlier Friday.

    SpaceX has requested waivers to use this signal range. AT&T says its proposal doesn’t do enough to prevent interference with other networks, saying in its filing that SpaceX’s “technical showings are woefully insufficient regarding the risk of harmful interference posed by their planned [supplemental coverage from space] deployments.”

    Though SpaceX and T-Mobile haven’t publicized a successful call from space that would demonstrate the plan’s lack of interference, AT&T noted that it has already made a surface-through-space call with its satellite partner AST SpaceMobile.

    AT&T hasn’t announced when its own consumers will see the benefit of its satellite partnership with AST, which aims to augment regular 5G service. It has the advantage that AST has been connecting satellite calls for years, while SpaceX’s network of microsatellites will need approval before they can carry calls. Verizon had also announced that it would use Amazon’s Project Kuiper satellites (none of which has been launched into orbit yet) to expand its mobile network.

    Meanwhile, Apple’s Emergency SOS system available only on the latest iPhone 14 series has been the only widely available satellite-to-cell system in use so far. Qualcomm’s Snapdragon Satellite service is expected to go live later this year for phones using the latest Snapdragon chips.

    Neither AT&T nor T-Mobile immediately responded to a request for comment.

  • Watch ‘Dungeons & Dragons: Honor Among Thieves’ From Anywhere

    Watch ‘Dungeons & Dragons: Honor Among Thieves’ From Anywhere

    Dungeons & Dragons: Honor Among Thieves’ eye-popping cast and rollicking adventure have reached the Paramount Plus streaming service. The PG-13-rated movie, based on the fantasy roleplaying game, brings together an unlikely crew for an epic heist led by the one and only Chris Pine.

    The release on the streaming service means there’s another option for those who haven’t made it to theaters to watch the film, which premiered exactly seven weeks ago, and don’t want to own it. Alongside Pine in the too-cool cast are Michelle Rodriguez, Bridgerton’s Regé-Jean Page, Sophia Lillis of the It horror films and Hugh Grant. The movie is a lot of fun — more of a Chris Pine vehicle than anything else — and it was bolstered by generally favorable reviews, according to Metacritic.

    Michelle Rodriguez and Chris Pine get into another scrape.

    Paramount Plus

    Here’s more on how you can watch Dungeons & Dragons: Honor Among Thieves, and why you may want to use a VPN if you’re streaming it.

    How to watch the new Dungeons & Dragons movie

    Dungeons & Dragons: Honor Among Thieves landed on Paramount Plus on May 16.

    If you’re interested in getting Paramount Plus, the service has two subscription tiers: ad-supported Essential and (mostly) ad-less Premium. Scream 6, another film that spent time in theaters recently, is also on Paramount Plus. You can still get tickets to see Dungeons & Dragons on the big screen.

    Sarah Tew/CNET

    Paramount Plus’ Essential tier with ads costs $5 per month and its ad-free Premium tier is $10 per month. There’s a weeklong free trial for both.

    As far as deals go, the price of paying for a year of Paramount Plus upfront is less than it would be if you paid for a monthly subscription for the same length of time ($50 for a year of Essential Paramount Plus, and $100 for a year of the Premium version). College students can get a discount on a monthly ad-supported subscription.

    How to watch the new Dungeons & Dragons movie from anywhere with a VPN

    Perhaps you’re traveling abroad and want to stream Paramount Plus while away from home. With a VPN, you’re able to virtually change your location on your phone, tablet or laptop to get access to the movie from anywhere in the world. There are other good reasons to use a VPN for streaming, too.

    A VPN is the best way to stop your ISP from throttling your speeds by encrypting your traffic. Using a VPN is also a great idea if you’re traveling and find yourself connected to a Wi-Fi network, and you want to add an extra layer of privacy for your devices and logins. Streaming TV can be a bit smoother with a reliable, quality VPN that’s passed our tests and security standards.

    You can use a VPN to stream content legally as long as VPNs are allowed in your country and you have a valid subscription to the streaming service you’re using. The US and Canada are among the countries where VPNs are legal, but we advise against streaming or downloading content on illegal torrent sites. We recommend ExpressVPN, but you may opt for another provider from our best list, such as Surfshark or NordVPN.

    windows-laptop-generic-express-vwindows-laptop-generic-express-v

    James Martin/CNET

    If you’re looking for a secure and dependable VPN, our Editors’ Choice is ExpressVPN. It’s fast, works on multiple devices, and provides stable streams. It’s normally $13 a month, but you can get 15 months for $6.67 a month by opting for ExpressVPN’s annual plan that includes three months free.

    ExpressVPN offers a 30-day money-back guarantee. Read our review of ExpressVPN.

    Follow the VPN provider’s instructions for installation, and choose a country where Dungeons & Dragons will be streaming on Paramount Plus. Before you open the streaming app, make sure you are connected to your VPN using your selected region. If you want to stream Dungeons & Dragons on more than one device, it’s possible you’ll need to configure each one to ensure you are signed in. Go to settings and check your network connections to verify you’re logged in and connected to your VPN account. Now you’re ready to open Paramount Plus to stream.

    If you run into issues with streaming, first make sure your VPN is up and running on its encrypted IP address. Double-check that you’ve followed installation instructions correctly and you’ve picked the right geographical area for viewing. If you still encounter connection problems, you may need to reboot your device. Close all apps and windows, restart your device and connect to your VPN first. Note that some streaming services have restrictions on VPN access.

  • Microsoft Bing AI Chat Widgets: How to Get Them on iOS and Android

    Microsoft Bing AI Chat Widgets: How to Get Them on iOS and Android

    Microsoft launched artificial intelligence-powered search on Bing 100 days ago, celebrating the milestone with a few updates to the system this week. One of those is adding a chatbot widget for phone screens across both iOS and Android.

    “We’re launching a new Bing Chat widget,” Microsoft said in a blog post Tuesday. “Soon, you’ll be able to click the Bing icon to land directly in the new Bing Chat experience, or click the microphone icon to verbally ask a question.”

    Microsoft in February unveiled Bing search powered by the large language tech behind ChatGPT, calling its search engine an “AI-powered co-pilot for the web.” Search results began incorporating info from OpenAI as well as Bing adding a chat window to help you with things like making shopping lists, summarizing PDFs, generating LinkedIn posts and giving advice to your queries.

    The Bing AI chatbot was opened to everyone with a Microsoft account in early May, though it was limited to the Edge browser on computers, phones and tablets and the Bing app. From this week, you’ll be able to use Bing AI chat without a Microsoft account, though you’ll be limited to just five chat turns per session (signing in gives you 20 turns with the chatbot).

    Tuesday’s news means it’s now available as a widget, too.

    Microsoft also announced it has brought AI-powered Bing to the Compose feature in the SwiftKey keyboard, “which will now draft text for you according to the parameters you suggest — not just the subject matter but also the message tone, format and length.”

    It’s additionally improved the quality of chats in other languages than English and added the ability to continue your chatbot conversation between your mobile device and your desktop.

    How to add the Bing widget to your Android phone

    1. Download the Bing Chat app.
    2. On your home screen, touch and hold on an empty space until your home screen zooms out.
    3. Tap Widgets.
    4. Scroll through the list or use the search function to find the Bing AI chat widget.
    5. Touch and hold on the widget.
    6. Slide it to where you want to place it on the Home screen.
    7. Lift your finger, and the widget will be in place.

    How to add the Bing widget to your iPhone

    1. Download the Bing Chat app.
    2. On your home screen, touch and hold an empty space until your apps jiggle.
    3. Tap the add (+) button, located in the upper left corner.
    4. Select the Bing AI chat widget.
    5. Choose the size you want the widget to be.
    6. Tap Add Widget.
    7. Tap Done.

    After Microsoft introduced the Bing AI chatbot in February, rival Google followed with AI Bard in March. CNET has broken down ChatGPT as well as Bing and Google Bard to work out which is the most helpful chatbot.

  • Start Your Project Off Right With the Best 3D Printing Filament in 2022

    Start Your Project Off Right With the Best 3D Printing Filament in 2022

    You’ve got the best 3D printer you can buy all set up and ready to go, but you can’t get started without some material. If you chose a fused deposition modeling, or FDM, printer — the most common type of 3D printer for hobbyists — you’ll need a few rolls of special plastic.

    The material we use for FDM 3D printing is called filament and it’s an easy material to pick up. There are, however, different types of filament, each good for certain projects and terrible for others. You’ll want to make sure you’re using the best filament for the job at hand, or it may fail.

    I’ve put together this primer of the different types of filament as well as choices of the best filaments from my favorite brands. This will be updated regularly and contains some great choices for you to start.

    A collection of awesome 3D printing models!A collection of awesome 3D printing models!

    James Bricknell/CNET

    It’s important to choose both the right type of material and the right brand of that type, be it PLA, ABS or something more exotic. Here are the best of each of the five main filament types.

    Read more: Best 3D Printers

    Those categories are:

    PLA is the easiest material to use to make awesome things.

    James Bricknell/CNET

    Polylactic acid

    Polylactic acid, or PLA, is the most common 3D printing filament and the easiest to use. Unlike most plastics, it’s made from corn starches so it is non-toxic and, in theory, compostable, though it takes an industrial composter to do it. PLA uses a fairly low heat — between 190 and 215 degrees Celsius (or between 374 and 419 degrees Fahrenheit) — to melt the plastic for extrusion so it is the safest of the filaments. Almost every FDM 3D printer in the world can print PLA.

    PLA pros

    • Nontoxic
    • No awful smell
    • Easy to use for a beginner
    • Almost universally usable on any FDM printer
    • Very cheap

    PLA cons

    • Can require a lot of sanding
    • Can easily warp in the sun or high-temp environments
    • Can be brittle

    MatterHackers

    Build PLA from MatterHackers is great for projects that require finishing (sanding, painting and so on). I have about 12 rolls of it in my workshop, and use it for large projects, including my Mandalorian armor or cosplay swords. The dimensional accuracy — how consistent the diameter is along the length of the roll — is good, though nothing mind-blowing. It’s well within the sweet zone.
    Post-processing is where Build Series PLA shines. It is simple to sand and holds paint well, as long as you use a good primer and filler first. Like all PLA, it holds together well using superglue and even takes putty and Bondo without complaint.

    Flashforge

    The color of this PLA is hard to describe, but it is beautiful. It has a purple-blue-green hue to it and looks like metal that’s been heated up a lot. Right now it’s probably my favorite-looking filament on my shelf.

    It’s also easy to print with, and because of the shifting colors it hides layer lines well. If you’re looking for a dark filament that you aren’t painting over, I’d pick up a few rolls of this today.

    MatterHackers

    For something completely different in the PLA world, check out Quantum by MatterHackers. Transitional filament, mixing multiple colors, has been around for a while, but it normally changes color across the length of the material. This causes it to change color as it goes further up the model.
    Quantum is actually two colors fused across the entire width, so you get an amazing transition from left to right. It’s absolutely mesmerizing, and I love using it for all sorts of different projects. From vases to giant articulated octopuses, it makes any model look breathtaking.

    Cookiecad

    I have been meaning to buy some of this beautiful filament for some time now, and I’m really happy I did. The color is almost exactly the same as Mint choc chip ice cream and the tiny flecks of marble color enhance the look even more. It prints great, with a nice glossy finish, and I found printing it at a higher temperature brings out that gloss really well.

    More importantly than the print quality though, I love it for the way it makes me feel. The color just makes me happy and reminds me of days at the beach with my kids. It’s gorgeous.

    Ataraxia

    Ataraxia Art already makes excellent PLA and flexible PLA but its new range of tri-color filament is some of its best yet. Tri color uses three colored filaments along its width to create a beautiful shimmering effect as you move the model so it’s perfect for projects you aren’t going to be painting.

    This PLA comes in four different color combinations and it’s now one of my favorite filaments to use.

    James Bricknell/CNET

    Rainbow filament tends to transition between colors very slowly. This means you often get only one or two colors per model. Creality’s latest rainbow filament has a much shorter transition, so you get a much nicer rainbow effect across your models. It looks great on this amazing dragon from Fotis Mint.

    Polymaker

    For projects you can show off without having to paint them first, PolyTerra might be for you. The colors are vivid, and because they are matte, you don’t lose details in the reflections like with shiny filament.

    PolyTerra also comes in recycled cardboard reels, and the creator, Polymaker, will plant a tree in the area where the roll was bought to help offset the cardboard used. This filament is still plastic of course, but it helps my conscience to use it.

    Ataraxia Art

    In this article about this flexible PLA I explained how, although this isn’t technically PLA, it does print much easier than TPU, a more common flexible filament. I used it to print an amazing Mandalorian Blacksmith helmet for my 4-year-old. She can’t break it because it’s so bouncy.

    This isn’t for newbies, though. It took a lot of trial and error to get the setting for my 3D printer right, and because it is so soft the accuracy can be pretty wonky. But for something that’s different from normal PLA, it is worth checking out.

    Acrylonitrile butadiene styrene

    ABS was one of the more 3D printing filaments a few years back, and it still has some excellent uses. The biggest downside is the toxicity. You don’t want to breathe in ABS as it melts, so you’ll need a well-ventilated area. That aside, it’s sturdier and more heat-resistant than PLA. Most printers can print ABS, but you’ll need a heated bed that can reach 100 degrees Celsius for best results and protecting your printing job in an enclosed printer is a good idea.

    ABS pros

    • Can withstand a lot of heat
    • Easy to sand
    • Can be smoothed with acetone for a perfect shine

    ABS cons

    • Its fumes are toxic so it requires ventilation
    • It needs far more heat to print than PLA
    • You will need an enclosure to get good results

    inland-absinland-abs

    Inland

    Inland makes good filament across the board and its ABS is no different. I’ve never had issues with the dimensions, and the final product has consistent layer lines. Sanding Inland ABS is a joy as the material can be wet-sanded to a smooth finish.

    You’re receiving price alerts for Inland 1.75mm Black ABS

    filumentum-absfilumentum-abs

    MatterHackers

    Fillamentum is one of my favorite ABS makers. The colors are always so vibrant, and while it costs a little more than the competition, it keeps that vibrancy even after the model is finished printing. If you’re looking for ABS that you don’t need to paint, Fillamentum is a great place to start.

    Polyethylene terephthalate glycol

    PETG is chemically similar to the plastic that water and soft drink bottles are made of, and is a great alternative to ABS. It has the heat-resistant properties of ABS without the toxic fumes and can be sanded much like PLA. Most FDM printers that can print PLA can print PETG, though it takes a little more effort to get right.

    PETG pros

    • Easier to print than ABS
    • Holds a finish well
    • Easier to store than other filaments

    PETG cons

    • Requires high temps, which can damage printer parts over time.

    Protomaker

    This USA-made PETG has an excellent glassy look that is hard to achieve in melted plastic. The aqua color is subtle and gives the appearance of a stained glass window when printed at the high end of its temperature scale.
    Printing with it was easy, though the roll is a little big for printers like the Bambu Lab X1, that has enclosed filament system.

    Red filament with phone standRed filament with phone stand

    Matterhackers

    The Pro series filament from MatterHackers is a much nicer product than a lot of standard PETG. Yes, it costs a little more, but it’s designed to help reduce some of the issues that filament suffers from. It reduces shrinkage, so the part you make is as close to the part you designed as possible. This is a great material for those who make 3D printed models for a living, rather than a hobby.

    overture-petgoverture-petg

    Overture

    Overture PETG is a favorite because it comes in an economical two-pack, making it ideal for multiple or larger jobs. I’ve used a lot of Overture products, including PETG and PLA, and they always print well. I once printed an 11-foot-long Masamune sword using Overture and it came out looking awesome.

    Thermoplastic polyurethane

    TPU is a flexible material that can make cool rubbery models. Most people use it to 3D print phone cases, but more serious modelers often use it to create connectors or flexible hinges to other materials. It can be a difficult material to work with and is best used on a direct-drive 3D printer such as the Prusa Mk3s, rather than a Bowden printer like the Anycubic Vyper. A direct drive printer places the gears to move the filament directly on the print head, while a Bowden setup has them on the frame of the printer.

    TPU pros

    • Flexible
    • Won’t warp in the heat
    • Available in fun colors

    TPU cons

    • Terrible for making solid prints
    • Hard to work with on budget printers

    MatterHackers Build Series Materials sit in the perfect balance between usability and cost. Yes, I’ve had failures with the Build Series, but once you get it dialed into your printer, you can make dozens of fun, springy models.
    I like to use it to make fun toys for my kid’s preschool as they can be thrown around with no fear of breaking into small, sharp pieces.

    Exotic filaments

    Exotic filaments are ones that are outside the normal five choices, or interesting variations on those choices. They’re often PLA mixed with carbon fiber or glow-in-the-dark chemicals and something that prints outside the normal parameters of a 3D printer. You’ll often need to upgrade your printer nozzle to use these. It’s advanced stuff, but I wanted to show you my favorite glow-in-the-dark filament, which is fun to print with.

    Amolen PLA

    Glow-in-the-dark filament normally comes in a standard “radioactive” green, but this beautiful roll transitions through multiple colors. It’s simply gorgeous.

    It’s also worthwhile to buy some replacement brass nozzles for your printer as glow-in-the-dark filament can chew them up pretty quickly because the glowing material is more abrasive than standard colors.

    Filament FAQ

    What filament should I start with?

    If you’re buying a printer for the first time, the best choice of filament is PLA. It is the easiest to print with, the safest in terms of fumes and the most readily available. Think about laying in a store of PLA when you first start. A 1-kilogram roll feels like a lot, but once you get the itch, materials get eaten up quickly.

    Are there different sizes of filament?

    Yes. There are two main thicknesses of filament and if you get them mixed up, your machine won’t print.
    1.75mm filament is the most common. It’s been adopted by most of the 3D manufacturers in the world and if you have an entry-level printer, it’s likely to run on 1.75mm filament.

    Some 3D printers still use the thicker 3mm style, though, so make sure you know which one yours uses before you spend a lot of money on the wrong material.

    Are all filaments toxic?

    When 3D printing with any filament, it is important to remember that you are essentially burning plastic. Inhaling that kind of thing is never going to be good, but not all filaments are equally bad.
    Of the four main filament types, ABS is easily the most toxic. You shouldn’t think about printing it unless you have a well-ventilated space away from your day-to-day living spaces. I have a workshop with a full ventilation system and the fumes can still be pretty bad.
    Both PLA and PETG are considered nontoxic, though you still want to keep your area ventilated as you use them. Both filaments are safe to print inside your home and while the fumes can smell pretty bad, they’re not classed as carcinogenic. While other forms of TPU can be toxic, the filament you use for 3D printing is considered nontoxic and nonreactive so you should be fine printing that as well.

Does the filament keep the same color after printing?

Normally yes. If your printer isn’t calibrated well, it could burn the filament, which would discolor it. But normally the color accuracy is pretty close.

A special note on clear plastics: You will not be able to get a completely translucent print with filament. The nature of the printing process makes any clear plastic misty and infill makes it blurry as well. If you are looking to print glass-like models, you will need a resin printer.

How we test filament

The testing of filament is mainly focused on a few details: Dimensional accuracy, winding precision, and printing quality. Winding precision is a visual test where I check to make sure the filament works well on the spool, without any crossovers that can cause snags while printing.
Print quality is done using a CNET calibration test that I use to test all of the 3D printers I review. When checking for filament quality, I’m looking for noticeable roughness and missing filament where moisture or other contaminants have interrupted the process of melting and cooling.

James Bricknell/CNET

Dimensional accuracy is perhaps the most important test as it measures the consistency of filament. As you move along, the filament changes in diameter will cause the 3D printer to over- or under-extrude filament. This creates noticeable scarring in your model, or worse, complete failure. You want the material to have the same diameter the whole way through.

To measure the accuracy, I take a 5-meter piece of filament from the beginning, middle and end of the roll and measure the diameter at four equally spaced points. I then add all of those measurements up and divide the total by 12 — the total number of measurements taken — to give me an average across the roll. Most modern printers use 1.75mm filament so you want the filament to be as close to that as possible.
Great filament has a variance of +/- 0.02mm, good filament is +/- 0.03mm and rough filament is anything +/- 0.05mm. All of the filaments we have recommended here are at least 0.03mm on average.

    I Tried an AR Laptop. It’s Way Ahead of Its Time

    A small keyboard and trackpad lies in my lap. But there’s no screen. Not that you can see, anyway. To me, I have a curved wraparound workspace with dozens of windows open. I’m seeing it on a pair of AR glasses (with prescription inserts) perched on my nose.

    I first tried the Spacetop in Las Vegas back in January, but the company that developed it, Sightful, is finally announcing the early-access product experiment now. I’ve seen tons of AR and VR headsets, but very few unique peripherals designed to work together with these future goggles and glasses. Instead of gaming or social experiences, Spacetop’s main pitch is to turn laptops into AR-assisted devices with endless virtual displays.

    If that sounds like a weird pitch, consider that I’ve already lived it. I’ve paired Meta’s Quest Pro to my laptop to extend its virtual monitors around my head, and plenty of solutions like this already exist using available apps. The interfaces can be clunky, and the hardware isn’t totally made to be mobile. Spacetop’s keyboard base, with its own Qualcomm processor inside, acts as a spatially tracked anchor that the AR glasses can follow and track the floating displays to. The tracking can work while in motion in a car or plane, and a button on the keyboard can make the floating displays vanish for an in-room conversation with someone, toggling the virtual screens on and off.

    This visualization of working on Spacetop is actually very similar to the experience of using it, except the field of view at any time is smaller (imagine viewing through a narrower window).

    Sightful

    The Spacetop comes with a pair of NReal Light AR glasses as part of its package, which need to be physically tethered to the keyboard to work. Sightful’s founders are planning for wireless options eventually, but found the tethered option more reliable for consistent tracking right now. Also, the whole concept could eventually work with other AR and mixed-reality headset hardware down the road.

    That would make sense, considering how many devices should be on their way: Apple’s, to start, and whatever Samsung, Google and Qualcomm are cooking up in the next year or so. NReal’s glasses are fine, but don’t work over my own glasses. Instead, I had to use prescription inserts, which Sightful will make for buyers of the hardware. The inserts I tried weren’t a perfect match, but were enough to appreciate that the display resolution was more than good enough for monitor readouts. The field of view, however, is narrower than most VR headsets: it can show something like a 40-inch TV screen as seen across a table, but I have to turn my head to see the other floating windows of other minimized browsers in the Spacetop’s Chrome-like software interface.

    Scott Stein/CNET

    Zooming into displays, or scrolling around, is all done through trackpad and keyboard work. The keyboard itself is the interface.

    Sightful’s team has experience in AR: Founders Tamir Berliner and Tomer Kahan came from Magic Leap, and Berliner also founded Primesense, the depth-sensing technology that powered Microsoft Kinect and which Apple acquired as the foundation to its Face ID TrueDepth camera.

    As Apple’s headset begins to imagine how mixed reality could work with other devices — perhaps iPads, or the Apple Watch — upcoming glasses and goggles will start to imagine working better with phones or laptops, and other tools to come. It makes sense that new peripherals would arrive as well — not just controllers, but tracking rings, wearable trackers and a new wave of keyboards designed specifically for mixed reality.

    I think Spacetop is a bit ahead of the curve here, and while it’s designed as a primary computer with its own headset, the future may belong to smart accessories that evolve from this idea to work with more headsets to come. If VR and AR are ever going to be more than just places for games, better work tools need to arrive. Spacetop is a pretty fascinating first step to what I imagine will be a lot more on this front.

  • Montana Governor Bans TikTok: What It Really Means for You

    Montana Governor Bans TikTok: What It Really Means for You

    TikTok lets people create and share short videos covering everything from beauty products and the British royal family to more serious social issues, and its users range from celebrities to students. But TikTok has been in the news lately not for its content, but for concerns related to its Chinese parent company, ByteDance. That controversy just heated up. On Wednesday, Montana Gov. Greg Gianforte signed Senate Bill 419, making Montana the first state in the nation to ban TikTok.

    “The Chinese Communist Party using TikTok to spy on Americans, violate their privacy, and collect their personal, private, and sensitive information is well-documented,” Gianforte said in a press release. “Today, Montana takes the most decisive action of any state to protect Montanans’ private data and sensitive personal information from being harvested by the Chinese Communist Party.”

    TikTok reports that it has more than 150 million monthly active users in the US. And a 2022 Pew study found that 67% of US teens aged 13 to 17 said they used the app, with 16% of all teens saying they use it almost “constantly.” So can Montana, the eighth-smallest US state by population, really ban its just over 1 million people from using the app? It’s complicated.

    For more on data privacy, check out CNET’s list of the best VPN services and how to stop iPhone apps from tracking you.

    Is banning TikTok really going to protect data privacy?

    The Electronic Frontier Foundation, a nonprofit digital rights group, called the ban “unconstitutional” in a Twitter thread.

    And an article from March published on the EFF site pointed out that nearly all social media platforms and online businesses collect a good deal of personal data from users, while noting that the surveillance and censorship practices of China make TikTok a special case.

    “Still, the best solution to these problems is not to single out one business or country for a ban,” the EFF wrote. “Rather, we must enact comprehensive consumer data privacy legislation. By reducing the massive stores of personal data collected by all businesses, TikTok included, we will reduce opportunities for all governments, China included, to buy or steal this data.

    Jason Kelley, the EFF’s acting director for activism, told CNET in a phone interview that the ban violates the First Amendment, which forbids government restrictions on free speech, and won’t protect data privacy, but will put an “enormous burden” on Montana as it attempts to enforce the law. But he doesn’t think that’s the point.

    “It’s not a law that is intended to be implemented,” he said. “It will waste a lot of taxpayer money and be litigated in court.”

    Why is Montana banning TikTok?

    TikTok’s parent company, ByteDance, is headquartered in Beijing. Some fear that data acquired by the app could be accessed by the Chinese Communist Party, and could pose a national security threat to the United States if the company is forced to share US user data with the Chinese government.

    In November, FBI Director Christopher Wray said the app could be used to “control data collection on millions of users, or control the recommendation algorithm, which could be used [to] influence operations if they so choose, or to control software on millions of devices.” FCC Commissioner Brian Carr last year called the app a “sophisticated surveillance tool.”

    The ban wouldn’t take effect if TikTok is sold to a company not based in “any country designated as a foreign adversary” by the US government.

    Montana’s ban is the first of its kind by a state, but in December, US lawmakers banned the app from government devices, and other countries have also restricted the app.

    What does TikTok have to say about the ban?

    TikTok has denied that it feeds information to the Chinese government.

    “There is no truth to the [Montana] governor’s claim that TikTok is associated with the Chinese government,” a representative for TikTok said in a statement sent to CNET. “The Chinese Communist Party has neither direct nor indirect control of ByteDance or TikTok. ByteDance is a private, global company, with roughly 60 percent owned by global institutional investors, 20 percent owned by the company’s founders, and 20 percent owned by employees — including thousands of Americans.”

    The statement from TikTok goes on to say the bill is unconstitutional and that Montanans should keep using the app.

    “Governor Gianforte has signed a bill that infringes on the First Amendment rights of the people of Montana by unlawfully banning TikTok, a platform that empowers hundreds of thousands of people across the state,” the statement reads. “We want to reassure Montanans that they can continue using TikTok to express themselves, earn a living, and find community as we continue working to defend the rights of our users inside and outside of Montana.”

    TikTok Chief Executive Officer Shou Chew testified before Congress back in March. He said TikTok has been working on an initiative called Project Texas, which he said would create “a firewall that seals off protected US user data from unauthorized foreign access,” and include oversight by a US company.

    What does the Montana TikTok ban involve?

    The Montana police aren’t going to break down citizens’ doors and stop Billings or Butte teens from uploading or watching quirky dances or funny cat videos. Instead of going after individual users, the state’s attempting to prohibit mobile application stores from offering TikTok within the state.

    So while the law does technically prohibit downloads of TikTok, it doesn’t mention fining regular citizens, just TikTok itself or whichever app store, Apple for iOS devices or Google for Android devices, allows Montanans access to it. The proposed fines are hefty — $10,000 per day for each time someone accesses TikTok, “is offered the ability” to access it, or downloads it. Again, those fines wouldn’t apply to the users, but the companies that allow them to get TikTok.

    However, the bill also includes even stricter rules for state employees using government devices. It says that “effective June 1, no executive agency, board, commission, or other executive branch entity, official, or employee of the State of Montana shall download or access social media applications that provide personal information or data to foreign adversaries on government-issued devices or while connected to the state network.” And third-party firms conducting business for, or on behalf of, Montana are now prohibited “from using applications with ties to foreign adversaries.”

    How will Montana enforce the TikTok ban?

    This is unclear. The prohibitions on state employees and agencies kicks in June 1, but the main part of the ban won’t take effect until Jan. 1, 2024. That gives the state some time to figure things out, and in the meantime, there will surely be lawsuits, likely from TikTok itself, and perhaps entities such as the ACLU.

    But as far as enforcement itself, there are some idea. The Associated Press reports that Montana’s attorney general has suggested the technology used to restrict online gambling apps could be used. Violations can be reported by anyone, and the state then sends a cease-and-desist letter to the company.
