The argument of the AI megacorps is that generated work is not "derivative" and therefore doesn't fall interact with the original authors copyright. They have invented a machine that takes in copyrighted works, and from a legal standpoint produces "entirely original" code. No license, be that GPL or otherwise, can do anything about that, because they ultimately rely on the authors copyright to required the licensee to observe the license.

They cannot violate the license, because in their view they have not licensed anything from you.

I think that's horse shit, and a clear violation of the intellectual property rights that are supposed to protect creatives from the business boys, but apparently the stock market must grow.
