A big difference with open models is that anybody can run and tune them any way they like. The real difference in philosophy is that Americans companies treat the model as the product, while Chinese companies see models at infrastructure you build products on top of. You amortize the cost of deploying it at scale by sharing knowledge and iterating quickly to bring the cost down.
I see absolutely no reason why CPC would choose to kneecap themselves the way the USG just did. Keeping open access to the models means that the whole world will be using Chinese based AI stack going forward. Only a government run by absolute imbeciles would do what the US did.
Even if everyone uses Chinese open weight models at somw point, how do you make money creating them?
This is just typical Chinese behavior. Flood the market with cheap or free stuff and wait for your competitors to die off. Then you have a monopoly. (Maybe you were implying that would happen, dunno)
I mean you could ask the exact same question about other foundational tech like Linux. And the real question here is what stops Americans companies from producing things cheaply and at scale the way Chinese companies do. You frame it as some nefarious tactic, but the reality is that they're just more efficient and American companies are unable to compete with that.
