They certainly seem intent on producing and distributing materials based on that licensed material, and stripping out the licensing and pretending it never existed.

That doesn't seem different to me. Copyright, inherits.

If its fair use, like the companies currently claim, maybe it is different. But I suspect that the insane push to create a copyright carveout in countries around the world, is not unrelated to a judgement that it probably isn't fair use.

Give me one example of something distributed by OpenAI that is copyrighted by a third party.
