US President Joe Biden has signed a bill compelling TikTok’s parent company, ByteDance, to sell or ban the popular social media app within nine months. The move comes amid concerns that TikTok poses a national security threat due to its Chinese ownership and access to US user data. ByteDance has refuted these claims and vowed to challenge the law in court. If TikTok is sold or banned, users will have time to adjust, but a VPN or parental controls may be necessary for continued usage or data protection.
