What TikTok could look like for users in the U.S. — and around the world — if it goes dark

With just days to go until the U.S. Supreme Court votes to uphold a ban on TikTok, the Chinese-owned social media platform is preparing to go dark on Sunday — and the 170 million Americans who use the app can expect some changes.

While U.S. users won't be forced to delete the app, it could become increasingly unusable. Carmi Levy, a tech analyst in London., Ont., expects "more of a fizzle than a Big Bang. But bottom line is if you live in the U.S., the experience is going to be a lot worse over time than it is now."

Here's what could happen to TikTok if a ban goes through:

Toronto cybersecurity expert Ritesh Kotak has a different hypothesis. He thinks that TikTok users will be able to click on the app, "but the screen wouldn't load. It might just be a wheel that continues to scroll, but probably chances are it's just going to be completely blank and you won't be able to use the app at all."

What about workarounds? Some users have suggested that they'll scroll through TikTok using a VPN, or virtual private network, which is a tool that lets you hide your digital location.

But that might not be as easy as it sounds. TikTok likely has other means of tracking a user's location, like using geolocation data from an individual's phone. And the U.S. government will likely put a mechanism in place that stops IP addresses belonging to TikTok from being accessed at all, says Kotak.

Users who circumvent the ban but get caught might be hit with financial penalties, but "we just don't know, because we don't know what the type of punishment is actually going to be," he added.

Content creators recently told CBC News what the disappearance of TikTok could mean for them. Once 170 million U.S. users vanish, what will TikTok feeds look like for Canadians and for other users around the world? 

"This is a global application, well over a billion users around the world. And they too will be affected because the American users of Tiktok form a significant audience for many of the global users outside of the U.S.," said Levy.

"Suddenly, the remaining users in other countries might find it no longer as valuable once all the Americans have disappeared or find some other app to use."

President-elect Donald Trump has demonstrated a willingness to save the app, and TikTok CEO Shou Zi Chew will reportedly attend his inauguration on Jan. 20, a gesture that aligns with other tech executives hoping to build a friendly relationship with the incoming administration.
