The fate of TikTok rests with Supreme Court after the platform and its parent company filed a suit against the U.S. government, saying that invoking PAFACA violated constitutional protections of free speech.
TikTok's argument is that the law is unconstitutional as applied to them specifically, not that it is unconstitutional per se, said Cornell Law Professor Gautam Hans. "So, regardless of whether TikTok wins or loses, the law could still potentially be applied to other companies," he said.
The law's defined purview is broad enough that it could be applied to a variety of Chinese apps deemed to be a national security threat, beyond traditional social media apps in the mold of TikTok, Hans said.
