> The AI training isn't borrowing from libraries and returning from libraries

Perhaps that's an important distinction here, I was really just trying to explain what I thought the commenter was trying to say. Calm down with the copy pasta walls.

But I still think that AI companies could make a very similar argument to the one Google made in your copy-pasta. The laziness I refereed to earlier is the fact that they haven't even tried. They could donate the books afterwards which would go a long way towards helping that argument in court.
