You still left out that it doesn't matter anymore, just like Anthropic/Facebook/OpenAI only really needed to read massive amounts of copyrighted data only once (and of course, they all did this illegally, which makes their current complaints more than a little ...). Once they have a large model trained on the data, they can just retrieve reasoning traces and copyrighted data from the previous model. In fact that is a training technique long used because it has better results that directly training on the original data.

In other words: even if the US (somehow) denies them access to the current OpenAI/Anthropic models, they'll be able to improve based on what they already have.
