Earlier quoted context omitted.
You would have no idea whether you got minus points for failing to make the jump to Gitlab.
You say that proudly? You'll judge a developer based on petty preferences, and then not do them the favor of telling them as much? Must be a blast working there...

That said, I have never nixed anybody for being only on Github. And, thank you, it is a blast, but mainly because we don't have meetings.
