Well, there go any such claims of dangerousness in future models, regardless of if they are true or false.
No one's going to risk building anything important on these models if the government will randomly order the use of the model to be discontinued by all foreigners, regardless of if they are in the US or not. Just a matter of a foreign company catching up to take the commercial market for such models (though, as the US often does, they'll ban the competitor, so actually we'll have a situation where the backend uses a different model in only the US).
