OpenAI now tries to hide that ChatGPT was trained on copyrighted books, including J.K. Rowling's Harry Potter series

Not knowing something is a crime doesn't stop you from being prosecuted for committing it.

It doesn't matter if someone else is sharing copyright works and you don't know it and use it in ways that infringes on that copyright.

"I didn't know that was copyrighted" is not a valid defence.

That's why this whole argument is worthless, and why I think that, at its core, it is disingenuous. I would be willing to be a steak dinner that a lot of these lawsuits are just fishing for money, and the rest are set up by competition trying to slow the market down because they are lagging behind. AI is an arms race, and it's growing so fast that if you got in too late, you are just out of luck. So, companies that want in are trying to slow down the leaders, at best, and at worst they are trying to make them publish their training material so they can just copy it. AI training models should be considered IP, and should be protected as such. It's like trying to get the Colonel's secret recipe by saying that all the spices that were used have been used in other recipes before, so it should be fair game.
