> Facebook, Twitter/X etc. all can be grabbed by Western courts
Have we tried to (whether for TikTok or the western equivalents)? As far as I know there is no political will to meaningfully rein those companies in because the politicians in power also rely on their misinformation potential and don't want to bite the hand that feeds/brings votes and misleads voters towards them.
TikTok has local subsidiaries in most jurisdictions through which they run their advertising business, which is just as vulnerable to court orders as its western competitors. If push comes to shove, their ability to accept payment from the West can be significantly curtailed which will put a major damper on their advertising business.
The concerns around TikTok evading western law enforcement is FUD that allows to divert the conversation towards a convenient scapegoat (China) instead of addressing the root cause that there's incompetence/unwillingness to actually act on the harmful effects of social media platforms, Chinese and Western.
