I disagree, the write up is overly verbose. If AI helped inflate it, that's worthy of conversation.
Rhetorical faults are consistently discussed when security disclosures and notifications come up. How egotistical are the finders? Does it deserve a microsite? Does it deserve a logo? Similarly, why is the vendor response so vague? Why does it seem so weasel-like? Did they lie in this one place...?
The problem with AI writing is that it doesn't have a voice, is not typically good, and interferes with the ethos and pathos the author is trying to develop. It's verbose, and typically telegraphs a lack of editing or real review.
That humans still care about these things isn't a problem for dang to sort out. It's something that authors should continue to think about carefully before putting out automatically-generated content under their name.
"Does it deserve a logo and a microsite" is one of those debates that happens on message boards that is otherwise pretty alien to the practice of vulnerability research.
If these are the problems (or, your problems), then it seems that it doesn't matter if AI wrote it or not -- just that the writing isn't "good".
