The US Supreme Court is likely to uphold a law banning TikTok unless it is sold by its China-based parent company, ByteDance, due to national security concerns. Chief Justice John Roberts and other justices expressed worries about the app's ties to China, while Justice Neil Gorsuch showed support for TikTok's free speech arguments. The law, signed by President Biden, could render TikTok unworkable for new users and updates, raising significant concerns about user data security and misinformation.
