Fuck AI

I mean what Meta did hardly counts as piracy imo. They used the authors’ works without their permission to train their ai for profit. There’s a big difference between that and individuals pirating books to read and maybe making those books more accessible to others for free

No it is absolutely not theft. It is not theft by law. (There's a reason why we have both "theft" and "infringement" in the lawbooks: they're different things!) It is not theft morally. (Theft removes the owner's ability to use something. Infringement does not. Infringement is a lesser moral crime if it is a crime at all.)

Please do not fall into the trap the IP holders like to lay by equating theft and infringement in your mind. You can have your opinions on whether infringement is bad or not (and the facts are … complicated with both sides being largely full of shit on this), but it is a matter of fact that theft and infringement are entirely different things.

Use the right term for the offence. Don't let IP holders' deliberate conflation to confuse the issue get to you.
