I haven't really taken a step back to critically think about using GitHub as a platform until now, but I do agree with the points in this article.

While I like the idea of a more distributed repository environment, I will miss the project discoverability, social aspects, and centralization that GitHub offers. It'll probably be awhile before I make a switch, but I will eventually.

Fwiw they're implementing federation, so bring it back some aspects of centralization without centralization
