Let me explain again since it went over your head the first time.

Companies, all else being equal, will choose less regulation over more regulation. If TikTok could release outside of the App Store where no one can inspect what they do, they would only release it there. Users addicted to the app wouldn’t suddenly stop using it but now they would be exposed to whatever TikTok feels like doing. They will choose the path of least resistance, not all the paths. It’s not that hard to understand.
