No, the new "adult thing" to do is try to control what other do and say, so that no one ever has to experience the traumatic effects of being offended.
I think many people here are conflating offensiveness and propriety. You don't have to be offended by something to find it inappropriate for a service that you run. (I don't find profanity offensive, but I also don't find it appropriate for business conversation. I doubt Googlers find a bird all that offensive, but the people making decisions apparently don't find birds appropriate for public G+ feeds. Oh noes?)
He, and you, and I, have no inherent right to do whatever we want on a private service. Their house, their rules. Maybe he should start his own social network (with blackjack, and...). He can call it CrunchPlaid. =)
