Well of course nobody believes that, there are a large number of great Chinese open source projects, and plenty of great Chinese contributors to open source projects. I have zero doubts that Chinese people are at least equally as capable of embracing open source as anyone else. It would be strange to suggest otherwise.

That said, though, I do have trouble believing the long-term story for open weights, anywhere. We do not need an evil government for open weight to "make sense", but I do think we need some government involvement for open weight to make sense in the long run. Otherwise, it's not 100% clear how they could be sustainable, and I don't think massive companies really can be trusted to just be philanthropic with no incentives indefinitely (or really, much at all to begin with.)

Chinese models being open weight does help them gain some Western mindshare, whereas for obvious reasons Americans would be very suspicious of running their source code and prompts through Chinese providers. (And I think that's justified, I just also think that American providers aren't really that much better in the long run, and you should prefer to not have to go through any provider for true privacy.)

The CCP encourages open source contributions from companies, you can see this in how much Alibaba open sources across their entire stack

Chinese tech leans much more heavily towards build vs. buy than the SaaS dominated West (where programmers are more expensive) so the positive externalities on their tech industry are more pronounced
