There is nothing wrong with calling some random person who chose to publish thing that is potentially viewable by the entire world, if they say something like it's not. You just have different occasions where you think it's warranted. It should happen to public figures, and it should happen to people whom you know, or whom you're in the presence of. Don't like that? It's my business to govern like the etiquette of strangers, yes. Iki yido, personal people like that are in your presence that you know, no, an twitter, what do you mean? I mean, but it's twitter. We do this all the time.
