Well the CCP does exert considerable control over TikToks parent company ByteDance. The CCP has already utilized data from TikTok to track protestors and other “dissidents”

No the CCP does not own Tik Tok but it might as well own it.
Unfortunately this situation is not unlike what the US government likely does. However, hopefully this precedence building policy recognizes that data privacy from 3rd party entities is needed. Will that standard be applied to US companies? Not likely any time soon but I’m optimistic.
There is no evidence that it is banned. ByteDance just made the same app for the PRC market
