The difference is "the various acts" in the US are things that are largely very hard to do, extremely limited in scope, and companies who dispute the government's propriety can (and do) go to court to fight it.
Sure "China bad, US good" is naive, but certainly not more naive than suggesting that companies and individuals have similar rights and protections as each other.
> and they need US govt approval before model releases
This is just not true and it would be a gigantic legal battle to make it true against the model companies' wishes, which is indicative of your entire misunderstanding here.
There was recently some announcement from the US govt itself (after the Mythos announcement) that they were pondering about allowing model releases from now on only after approving them.
So it may not be strictly true for the moment, but it is certainly something that the current US govt can mandate at any time.
