TL;DR - We don't care about most open models. They are weak, and we don't care how they're used.

We care about specifically Chinese models, because China distills our models. And that's real competition. So we want to ban those.

PS. Oh yeah, in case any open non-Chinese model will one day be good enough to compete with us, we will want to ban you as well, just FYI.

Kthxbye.
