I doubt it. I don't see how more developer agency is a bad thing. If anything, more people will start using Github earlier on in their development cycle and Github will be the obvious platform of choice for when those projects are ready to go public. On the contrary, I think we'll probably see less trash and more quality projects on Github. Besides, I wouldn't want to live in a world where people want to do X (private repos) but are forced to do Y (public repos) because X is not feasible. Now X is feasible and the landscape will more accurately reflect developer intentions.
