IMO if TikTok can operate in the US, then Twitter, FB, etc. should be allowed to operate in China. It's the lopsided (potential) to influence the other market/populace that doesn't sit well with me.

Which specific US regulations is TikTok currently violating, and where is the hard evidence to support that?
Answered in the article.
Which specific (future, hypothetical) regulations should TikTok be in violation of, and on what basis?
