I disagree with the overall premise: Before the acquisition, GitHub had to figure out how to monetize at some point. Now, even though their parent company does some shitty practices with their other software (Embrace, Extend, Extinguish, MS Windows), it's a stretch to assume this will also translate into making GitHub worse: Being worried makes sense but I remain optimistic about GitHub.

I think you have some nostalgia about Github's stability before the acquisition.
