I agree with you when you are talking with a human in good faith. I disagree when it comes to large corporations and government officials. Often times theres a lot of red tape you have to get through and create documents that nobody on their side is actually reading. Usually this is just to discourage people from completing the action they are trying to accomplish. LLM generated content has gotten me back improperly held taxes and generated multiple extension requests where the receiver just had to check a box that they got it.
The position I think I can most simplify my beliefs in to is "it should have taken you longer to write something than the person receiving it is going to spend reading it."
That position still fits your scenario, where if they're not actually caring enough to read it then you don't need to care enough to write it, but for something like this targeted at a technical audience it's a higher bar.
Also of course the accuracy of the writing is relevant in both cases, which is something LLMs are absolutely worse than humans at, as noted in some of the comments here this article had the LLM hallucinate the existence of macOS 25 which is a mistake no human would have made while writing such an article entirely by hand.
