The author did not do this. The author thought it was wonderful, read the entire thing, then on a lark (they "twigged" it) checked out the edit history. They took the lack of it as instant confirmation ("So it’s definitely AI.")
The rest of the blog is just random subjective morality wank with implications of larger implications, constructed by borrowing the central points of a series of popular articles in their entirety and adding recently popular clichés ("why should I bother reading it if you couldn't bother to write it?")
No other explanations about why this was a bad document, or this particular event at all, but lots of self-debate about how we should detect, deal with, and feel about bad documents. All documents written by LLM are assumed to be bad, and no discussion is attempted about degrees of LLM assistance.
If I used AI to write some long detailed plan, I'd end up going back and forth with it and having it remove, rewrite, rethink, and refactor multiple times. It would have an edit history, because I'd have to hold on to old drafts in case my suggested improvements turned out not to be improvements.
The weirdest thing about the article is that it's about the burden of "verification," but it thinks that what people should be verifying is that LLMs had no part in what they've received. The discussion I've had about "verification" when it comes to LLMs is the verification that the content is not buggy garbage filled with inhuman mistakes. I don't care if it's LLM-created or assisted, other than a lot of people aren't reading and debugging their LLM code, and LLMs are dumb. I'm not hunting for em-dashes.

edit: my 2¢; if you use LLMs to write something, you basically found it. If you send it to me, I want to read your review of it i.e. where you think it might have problems and why you think it would help me. I also want to hear about your process for determining those things.
People are confusing problems with low-effort contributors with problems with LLMs. The problem with low-effort contributors is that what they did with the LLM was low-effort and isn't saving you any work. You can also spend 5 minutes with the LLM. If you get some good LLM output that you think is worth showing to me, and you think it would take significant effort for me to get it myself, give me the prompts. That's the work you did, and there's nothing wrong with being proud of it.
