I don't think this is what they're talking about. AI should be allowed IMO if it's an extension of the poster's humanity and not just a whole-cloth LLM generated song. The hardcore anti-AI crowd doesn't even know these types of uses exist, they just decided early on that they don't like fully generated stuff and are throwing out the baby with the bath water whenever AI is mentioned.

If you posted your AI assisted music (even with a policy in place) I don't think anyone would call it out or even notice, FWIW. In this climate I wouldn't even mention AI involvement.
