Not the entire U.S. population is on TikTok. Even if a significant percentage are, your argument is that they cannot think for themselves? It is widely known that TT is Chinese owned/controlled yet Americans still used it. Even a regulation requiring disclosure of that fact each time you open it would be fine. But an outright ban on the app itself? This is a huge "feel good" moment which will not improve any aspects of the social media environment in the U.S.
