I agree, but the problem comes back to how to evaluate quality at scale. That is very hard. It’s easier to just say no AI because that at least turns off the fire hose.
It sounds like they are even rejecting submissions where they even get a whiff of ai being "consulted" though. That's not quite the same as turning off the firehose.
The discourse around AI in the arts, and other creative and craft fields, is utterly identical to the discourse around photography when it came out to the point that you could search and replace terms and have the same dialogue.
