Why would you even believe the opposite? US spooks have been amassing vulnerabilities and relying on them for decades, they literally pioneered it in the 90's if not earlier. Everyone does it now but the US is the biggest of them all. Surely this devalues a lot of what they did. Moreover, the way the US government handled new capabilities, and OpenAI's training policy (they are in bed with the government) just scream "we want to create weapons for cyber-offence and deny them to everyone else"
It might not be the reason, but of course it's a contributing factor.

Good thing I said nothing of that (especially nothing about China). Reread it again to understand you built an incredible strawman and ignored my last sentence.
Well we know that the US government is pushing to restrict access to such models while the Chinese are publishing them for free, so it's mostly a matter of motivations, not the actual facts of the matter. And the USG has a documented history of unsavory behavior (including toward its own citizenry) in that area.
So we might ask if one of the reasons the US is being the bad guy is it's usual spying antics, and we're left asking why China is being the good guy.
