Why did you point at the em-dashes? It looks very much as though you're accusing the author of an update that was also generated (possible but they seem sincere enough about wanting honest feedback on the content, and making changes for that). Or you're saying the author - and maybe everyone in general? - should no longer use em-dashes because they're a LLM smell. Yeah I'd feel offended too. It's a real pity I can't find em-dashes on my keyboard, or I'd stick them in this comment.
