Justice Department tells court to reject TikTok's appeal over alleged data collection on US users

The US government has accused TikTok of posing a national security threat due to its access to vast personal data of citizens, citing concerns that the app's Chinese ownership could allow for the collection of bulk information on users based on their views on sensitive social issues such as gun control, abortion, and religion. The government claims that TikTok's parent company, ByteDance, uses an internal system called Lark to gather information on users' content and expressions, including their views on divisive issues. This has led to a lawsuit filed by TikTok and its creators seeking to block the law, with the government set to file a classified document with the court to support its claims.
