I'm just waiting for GitHub to be bought up by MS and turn into Sourceforge 2.0.
github is loosing money like crazy while gitlab and bitbucket are actually profitable.
Sure it's possible but I don't get it. Don't forget as more of these OSS projects take advantage of GitLab's free repositories the more money GitLab will lose.
They're not expecting to be profitable right now but their loses have risen quite a bit.
