Like the river finds the sea, people will find a way around it. Satellite connections, just as an idea.
Anything a chip does can be backwards engineered to fool it. People will break your proposed surveillance chip eventually.
Most of these companies are maybe US-owned to varying degrees but they don't produce everything in the US. Also, they would put a very high price on these government mandated chips for two reasons: 1) government has deep pockets and 2) it would keep them away from very profitable so-called AI biz opportunities.
The pandy has shown us that with a few disruptions in the supply chain, any system that requires a cryptographic chip check to function can be sent to hell in a handbasket. I forgot if it was HP or Canon or some printer company had to teach its customers to bypass, i.e. hack their own cryptogtaphic chip checks because they couldn't get more chips and otherwise the printers wouldn't print. A few disruptions could also affect the censorship chip supply chain.
The great firewall of China has also shown how creative people get to get their message across. If it's not just human censors but also so-called AI censors it will just take creativity to a new level. Necessity is the mother of invention.
So there are some reasons why you might be worrying too much. I think another one is much broader. The majority of Americans did not vote for the current president. If he started censoring the internet now there would be Civil War II - Now It's Digital. The reason why Russia or North Korea can censor their people much easier is because they have never had or only on paper a brief period of liberty and rule of law. It will be much harder to control the US population. There isn't just the one media outlet, the one ISP, the one judiciary to dominate. It's splintered. And populated by feisty people, some of them armed. You couldn't pull off what you suggested without much more support for 47. And he seems to be losing it more than gaining these days.
Normally, when somebody on the internet starts a question with "Am I the only one ...?" my first reaction is to say no, of course not. This is the first time that I really need to question that conviction. I think you just might be the only one!
