There is no reason why they couldn't license the model to Friendli/Fireworks/etc and have it hosted in the US to alleviate this concern.
I don't know about this model specifically, but other china models did not have the limitation. It was purely on the hosted end, tacked on as a self check while the text was generating. Did that change?
The reason is to create domestic demand for Chinese AI chips so they can eventually be free of NVIDIA.
