The US Supreme Court on Friday unanimously upheld the federal law banning TikTok beginning Sunday unless it’s sold by its China-based parent company, holding that the risk to national security posed by its ties to China overcomes concerns about limiting speech by the app or its 170 million users in the United States.
A sale does not appear imminent and, although experts have said the app will not disappear from existing users’ phones once the law takes effect on Jan. 19, new users won’t be able to download it and updates won’t be available. That will eventually render the app unworkable, the Justice Department has said in court filings.
The U.S. has said it’s concerned about TikTok collecting vast swaths of user data, including sensitive information on viewing habits, that could fall into the hands of the Chinese government through coercion. Officials have also warned the algorithm that fuels what users see on the app is vulnerable to manipulation by Chinese authorities, who can use it to shape content on the platform in a way that’s difficult to detect.
TikTok points out the U.S. has not presented evidence that China has attempted to manipulate content on its U.S. platform or gather American user data through TikTok.
