A US appeals court upheld a law mandating TikTok's sale to a non-Chinese owner or face a US ban, rejecting TikTok's claim that this violates free speech. The ruling stems from national security concerns over potential Chinese government data access and content manipulation. TikTok plans to appeal to the Supreme Court, arguing the law is based on unfounded fears and is an unprecedented restriction on speech. The law's supporters contend it's necessary to protect US national security. The Supreme Court will decide whether to review the case before the ban takes effect.
