Private use of the copyrighted works is pretty much a separate topic entirely.

And while the law isn't settled on the topic, it's wrong to argue AI training is something that happens entirely in a private setting, especially when that work is made available publicly in some form or another.

Sure, there's a problem with the current copyright laws that has to be addressed. It's quite similar to the "TiVo loophole" in OSS licenses. It was addressed, and certainly not in favour of the loophole exploiters. That one could be fixed on licence level because it was ultimately a licence question, but the AI training question, however, needs to be taken to the legislation level. Internationally, too.
