I disiagree with your (1). I would say that "It is the correct way to provide a reference to a person who you also want to see your tweet."

But I don't think we can come to meaningful agreement on that.

I also don't expect people to tell me directly about every problem they have with my behaviour, or everything I do that's annoyed them, only the ones they consider worth it. People talk about other people all the time, and only occasionally is it worth trying to effect change/have a socially difficult conversation with them.
