It’s crazy to me that people such as you unironically believe the position you’re saying that American companies are easier to crack down on.
We are literally seeing concrete proof in action that domestic companies are much harder to crack down on or regulate. They are much better positioned to lobby and are currently using their immense political power to protect themselves while removing their foreign rivals. There isn’t even talk of taking action against them because they are so politically powerful.
The problem with applying existing laws is then you’re under the regime of rule of law, and TikTok could escape by complying with the law like anybody else.
This is a xenophobic witchhunt, though, and that won’t do.
