To me this is the biggest thing.

I'm under no illusions that the US is pursuing this for altruistic reasons, but fundamentally I do think it's ridiculous that China bans western competition, yet the west rolls over and allows Chinese companies, or even the Chinese government, to buy out western companies, to enter the market and compete, and to compete using massive state subsidies or slave labour that kill domestic competition.

IMO it's entirely fair for a country to say "you're banning our companies? Ok then we're banning yours."

And I do also agree that China uses the data they collect for nefarious purposes. Be it training language models so they can better track and shut down dissenting voices at home, or spreading misinformation amongst other nations. I just wish the US would also clamp down on the privacy policies of domestic companies too.
