Seems reasonable?
Mainland Chinese are amazing engineers, can improve almost anything they get their hands on. They are also absolutely terrible at basic science, because that needs creativity which implies being too clever by half, which is politically problematic. Their moon landers and oribiters are the best of stolen NASA and ESA tech. And in this case, their AI is stolen tech with incremental improvements. Which they are absolutely fantastic at.
But it's really not an open source problem. If it weren't open source they'd steal it anyhow, that's what they're the very best at, and have been for 50+ years. That has literally been their government policy.
