To be fair, has he ever said that his family don't know? He's been droning on about "certain people" not knowing so it's possible that he IS already out to his family (or at least immediate family) but other people such as friends / extended family don't know.

Surely in this day and age, his school friends, at least, won't care?

It does seem kind of put on TBH and I imagine he told all of the "important people" before he went in, specifically planning to announce to everyone else whilst in there.
