Ya, a bit, I guess. I just don’t think talking down to someone is ever really a good way to communicate (unless the interaction is in fact adversarial and that’s the whole point). That being said I suppose I also get that sometimes it’s desirable to express exasperation, even if it’s not constructive or polite.
It is terribly worded, so it’s unnecessarily confusing and unclear, but it means ‘nobody says (or does) anything’, thus indicating that the second action is unprompted.
