Not this exactly, but IMO they're saying that since the text is presumably AI-generated, it kind of can't be beautiful? Or shouldn't feel beautiful? Or it's beautiful, but... it's AI-generated and thus "bad", not the right kind of beautiful. Or "it's beautiful, but that's because it's AI-generated", which is again not good for some reason.
I agree, I think that's a good summary of the comments.
It's more like: Person: Finds the article beautifully written. Comments: Doesn't find the article beautifully written.
Now Comments looks less like an unreasonable control freak and more like they're just someone who has different ideas about what's beautiful.
