Yep, that second part of my comment was an article I read about OpenAI and my mind mixed it up with Anthropic. My mistake.

In a sense, what eventually gets legalized through settlement or what doesn't provoke a lawsuit isn't that relevant.

The process of creating an LLM involves taking and processing a massive amount of human generated data, roughly all the world's literature/thinking/etc. A large portion remains within these systems. Aside from the legality, ethically that shouldn't belong to any one company.
