The US is 'looking at' banning TikTok and other Chinese social media apps

But how would that apply to the app stores? They have non-US customers wanting non US sanctioned businesses?
Obviously they could terminate individual corps them if they broke criminal laws, but the reality is that almost anything that tiktok’s surveillance has done has been done by the US social networks at this point as well.
China is just as right to be concerned about our companies being NSA backdoors as we are worried about TikTok.
That said, I (not a lawyer) think it depends on how they do it. If they can compel Apple and Google to remove TikTok from the app stores (which I think they could with help from Congress), that would likely be enough to kill TikTok in the US.
Sorry, in all seriousness though, I'm sure there's a legal pathway for any action the gov't wishes to take here [1].
