They made a code-of-conduct. It pandered too strongly to the list-every-under-privileged-class attitude including explicitly rejecting the concept of "reverse discrimination" and so the reactionary folks who want to insist they aren't sexist and hate any moralizing or politics that challenge them etc. got up in arms. It was all a stupid side-show and had nothing to do with anything that matters to GitHub's basic services or business model. Most people never noticed either way.
