This isn’t a job. They are a user like you who happen to also volunteer to mod because someone has to. They have just as much right to share their opinion as you do, and they did it politely. Besides, they didn’t even start an argument, they just shared an opinion, confirmed it, and then clarified again; all of it in a polite manner.
Anybody could goad a mod like that to misusing their authority
They seem to have handled the situation just fine and even left the report for other mods to handle. I really don’t see what the big issue is.
