If an article is badly written or AI-generated, there's value in that being pointed out in the comments. It can save people wasting time, and ideally, discourage people from posting low quality content. That's a large part of the point of a site like this.
If the community upvotes AI-genraated content to the front page, I don't see why it should automatically be penalized. (I respect your own opinion, which is why I suggest flagging the submission).
But clearly there's a reason it was upvoted if it's on the front page. Why ignore that fact... clearly the community thinks these articles have value if they're upvoted.
(Also, "it's AI, bad article" is just a weak complaint that can't be proven right or wrong - if you dislike it, share why you dislike it, e.g. lacking specific information, shallow depth, something other than "don't like it because AI")
