I heard a bunch of explanations but most of them seem emotional and aggressive, and while I respect that this is an emotional subject, I can’t really understand opinions that boil down to “theft” and are aggressive about it.

while there are plenty of models that were trained on copyrighted material without consent (which is piracy, not theft but close enough when talking about small businesses or individuals) is there an argument against models that were legally trained? And if so, is it something past the saying that AI art is lifeless?
