The problem with hard pushes in the aftermath of really bad PR is that it's very easy to over-correct and wind up creating a new problem for yourself. It seems like Github is well on their way to just that with how they've implemented their diversity efforts. A lot of those quotes are truly scary, and are priming the pump for some very nasty lawsuits over hostile work environments that will only wind up creating new PR problems. And if those quotes are any indication, it's unlikely that someone is going to be able to slam on the brakes and stop things from getting further out of hand.
