China does have its own set of cares, they may be different than ours but they still exist. If some open Chinese model goes nuts and posts Winnie the Pooh memes everywhere in China you should expect said models to get yanked off the market, and said creators might end up with a rope around their neck.

Low risk. The western AI models censor even more wrongthink than the chinese ones, not even kidding. Besides, once we have the weights, we can just undo the censorship.
