Github is SaaS and its value lies in its userbase and network effect. They do license out the github software product, but I imagine that that's a relatively small section of their money intake, and there are plenty of opensource alternatives (gitlab, gogs/gitea, others). They would probably more than recoup the costs with the goodwill they'd get.
