I would say Acotar and Tog are less Guilty than Fourth Wing is due to the earlier publication. But unfortunately a lot of the fan base is not artistic and have never been in a fandom before so they flock to Ai.
Why are so much of the ACOTAR, TOG, and Fourth Wing fandoms so obsessed with AI slop? I'm not in them, and I have my own opinions on the books and a theory of my own, but I'm just so curious. AI slop is insanely prevalent when I come across fan content.
