If you're outsourcing your writing to AI, I assume you're outsourcing your thinking to it as well. And I don't really care what some weighted average of all human text written on the topic "thinks."
AI writing is fine, but you can't just stop on the first draft, any more than you can while AI coding (in fact, even less so - your coding is read by computers and to an extent either works or doesn't; your writing is for humans, and not only needs to convey ideas but also needs to hold the reader.)
Shipping an unedited draft is lazy. Advertising and SEO filler that nobody will ever read can maybe get away with it, but if you're writing for humans, _READ_ the output critically and edit.
My argument is that randomly accusing something of being AI and pretending that it's bad merely because you think it's AI, is not good/good faith. Whether you think some writing is AI or not is besides the point. If the writing sucks, explain why. Not everyone shares your position that if something is written by AI it's automatically bad.
And for the record, you can have a lengthy conversation with an AI to communicate your ideas and then use the AI to draft the message. It'll have AI tells in it, but so what?

"That's literally just the output from a random word picker."
"Don't engage with the mechanism of production! Engage with the content! If it's bad, explain how it's bad! Not everyone believes the output of a random word picker is automatically bad!"
