Copyright is a bad idea in the first place, and should just be thrown out entirely; but that isn't the whole picture here.

If OpenAI is allowed to be ignorant of copyright, then the rest of us should be allowed, too.

The problem is that OpenAI (alongside a handful of other very large corporations) gets exclusive rights to that ignorance. They get to monopolize the un-monopoly. That's even worse than the problem we started with.
