I don’t think that’s the case. It’s more of a marketing/market incentive. It’s great pr to be associated with the most famous project, way less so to be associated with a fork, at least until the fork becomes widespread and well recognised.

GitHub does make it fairly easy to fork a project, I wouldn’t blame the situation on github.
