I was a paying GitHub customer, but they had such a crummy private repo policy at the time (I think only 5 private repos were allowed) it forced me to make poor technical decisions: "I'll delete this github repo, keep my local copy, to open up a slot." I switched all my private repos to gitlab and stopped paying for github and was happier for it.
Later github changed its policy to something saner, but I never switched back to using github for private repos. This decision by gitlab even if it's rescinded, however, might give me the impetus to do so.
