Why do you care about geopolitical implications? (I don't see how it supports your argument, sorry.)

What do you think my argument is?

China isn’t releasing open weight models for the good of humanity. They are releasing them to undermine US companies financial viability.

I care about that because that competition affects me.

I don't know what your argument is. Maybe some US companies won't be financially viable - so what? I mean if it affects you, you have stake in those companies, fair enough. But it's not a geopolitical problem - most US citizens even (not to mention the rest of the world) will be better off if they have access to public models.
