Well I had assumed that GitHub was profitable, since it used to be independent, and it feels like it should be profitable right now. But I tried Googling "is GitHub profitable" just now, and the first few results seem to suggest that either it's still losing money or that nobody knows. So I was likely incorrect about that point, sorry.

GitLab does the same thing, and they are definitely profitable [0], so that on its own isn't necessarily a barrier.
