The thing about strict professionalism is that it avoids the problems of bro-culture while simultaneously preventing issues from blowing up.
As of now, Github has pretty much alienated everybody. They've pissed of activists by firing Coraline and some of the stuff they've done in the past. They've pissed off "broflakes" by some of their other more recent cultural changes. But now they're starting to piss off people who may or may not care about social justice, but who definitely don't want the defining topic in the OSS community to be social justice. I think this is a game you can only win by refusing to play.
