Sure, or with patches broadcasted on radio, scribbled on napkins etc. I don't think you intended to counter my argument but in case anyone is interested in elaboration: my point about centralized/decentralize is that using github doesn't necessarily centralize your work. It's only central in the sense that any other remote repository is: if you can't access it you can't. If github dies, copies of the repository may still exist on a million other computers and any of those can be used as a basis for further collaboration by a wide variety of means. From a peer to peer perspective, github is just a peer like any other.
