I think you make many good points. Slight tangent: Why isn't EU more concerned about TikTok? While it is very difficult to prove, various studies have demonstrated that TikTok pushes more content favoring the Chinese Government (CCP).
TikTok never does that.
Does that violate EU law? (Serious question, I really don't know)

No doubt that it became an argument by some more recently, but it was just another straw on the already broken camel's back.
The tinfoil hats come out pretty quickly when China is mentioned but Occam's razor still applies here.
