I sort of get this PoV, but on the other hand…
If China had any information about you that was valuable for any purpose whatsoever (trade an intelligence tip to a corrupt businessman in a mafia state?) its government could do so with no legal or political safeguards.
The US government has legal safeguards against this, and would face _massive_ potential political risk for doing so against one of its own citizens.
The US government literally steals cash money from its citizens and faces no repercussions whatsoever. If you carry cash with you in the US, you're in absolute danger of having it confiscated by the police as "drug money" and never seeing it again. You can claim the US has "legal safeguards", but until they're actually tested, it's just a supposition.
You should look up how Israel actively fishes LGBT palestinian people using fake dating site accounts, and threatens to out them in order to force them to contribute intelligence.
The US is clearly not that compromised. But they're not exactly clean either, considering some of the stuff that happened in central America.
Only in the sense that, as a US citizen who has no desire to travel to China or Russia, I don't feel all that worried that either country is going to do anything bad to me directly.
But if I lived in either one of those places... whooooa boy. I'd have to be a different person to not get in trouble. And I wouldn't call myself much of an activist or pot-stirrer, really. I feel bad for people who want to show public dissent of their government in China or Russia but can't (or do, and end up in jail), and for people in marginalized groups that the government doesn't like.
