I don't understand why this is such a shocker to some of you. China is not and has never been a good guy. Neither is the US. It is the US best interest to hold certain strategic technology as secret and prevent any other nation from having access to it. Whether this is by banning export of EUV machines or by restricting access to Chinese AI, both are normal political moves.

The issue with dealing with a country whose culture is more transparent (US) than closed doors hush secrecy (China) is that stuff like this comes out and people have opinions about it. China on the other hand keeps quiet about this stuff and instead spreads propaganda about how great their country is.
