Git doesn't need a hub.

But, even though the Linux the project created git specifically for their own workflow, and is in the running for the largest and most complicated decentralized software project ever known, they still operate git.kernel.org. They still have a central master repository server.

Just because git clone gets you a first class copy of the repository doesn't mean you don't need a source of truth or a centralized master to operate and coordinate the project. Control is not the totality of the benefits of centralization, and we should not confuse the structure of the tool with the best structure of a project that uses that tool.
