This is a consequence of centralization. The canonical project sites and repositories should not be on GitHub.
Fanatics who believe otherwise will still clone those projects so that they are on sacred ground, but the practice should be frowned upon and fought against.
Another detrimental effect of GitHub is that they have trained users to accept public "forks" (a misnomer) as the usual way to contribute even trivial patches.
This lowers the bar for accepting and trusting non-official repositories.
GitHub has devalued the brand of large projects and has introduced the age of industrialized software development by creating an addictive environment where software politicians thrive by manipulating their social networks and working on their personal brand.
