Would be very hard to demonstrate that they did that. If all employees move to some country with a slow legal justice system and strong labor laws, they also recreate the training data because that can be transferred, they can train another version in said country which is perfectly legal.

Can you demonstrate beyond any reasonable doubt that the model weights have been transferred? No. Will the EU judges move to extradite said individuals (and many are EU citizens)? Also no, especially in the face of spurious accusations. And even if they were open to, you can stonewall everything and you will probably outlast any US administration pursuing that.

Well, force is a strong word… it’s still just accords, that the US doesn’t seem to be valuing lately… so if they say no, what’s the US going to do? Start a war over a company?
