Also another thing is when Github changed its licensing model it really hurt those of us working on small budgets like at non-profits or in education. https://venturebeat.com/2016/05/11/github-changes-pricing-un... For example, I worked at a public university where we had student workers. I could convince our dean to pay per repo but once it was per user we had to migrate off Github because we couldn't afford it. Migrating off took up a lot of my time.

I agree with this, also another issue with Github's dominance is silly recruiters now think a github profile is the best way to evaluate candidates. Sucks for those of us who use self-hosted revision control, Gitlab, or Bitbucket at work.
