Frankly, this kind of meddling just makes it more appealing to use Chinese models. Chinese models are often open-weight, meaning that they're basically immune to foreign meddling - if China decides tomorrow to "cut you off" you just need to find some other provider that's offering those models and buy access from them instead. Or if you're a big enough organization, just rent or buy some hardware and run it yourself.

This sort of meddling shows that the US government is eager to weaponize access to AI, and if you're dependent on American models there are no other places you can run them.
