But that's literally anathema to the spirit of GPL. Copyleft exists only as a reaction to copyright which is sadly ingrained in legal systems, but the original thought about free software, at the time of GPL inception, is that in an ideal world, copyright shouldn't exist for software ; it's leveraged by GPL only to protect against abuse of copyright holders that could close open code, which is thus made impossible "legally" with the GPL. AI makes this distinction fal into "practically" as pretty much anything is "open" for individual use now (e.g the only use that matters).
