The TikTok ban bill, recently passed by the US House of Representatives, could lead to a nationwide ban on the app. The legislation requires ByteDance, TikTok's Chinese parent company, to divest its stake in the app within nine months or face a ban from US app stores and web hosting platforms. The bill is part of a broader concern over national security, as it is feared that the Chinese government could access user data or push propaganda through TikTok. While the bill has been approved by the Senate, it faces potential legal challenges that could delay its implementation.
