You gotta remember there are people working at these companies with their own motivations, beliefs, and values. And to the extent that their government allows them to, they will act on those.

I think the people in the Chinese labs have a different set of motivations, beliefs, and values that make them more amenable to sharing AI as a common good rather than some economical advantage. I've heard that workers in the Chinese labs share far more knowledge between themselves, and the narrative around AI in China is different from what we see in the USA. So it is possible, I believe, that the labs are to some extent releasing open models "for the good of humanity", or at least they believe it is the right thing to do.
