We like to pretend Ethereum and Bitcoin are controlled by the code, but they're not. They're controlled by their communities, which decide what code to run. That's how it's always been.
Indeed this is the elephant in the room with the more ardent libertarian niche; the community as a whole has beliefs of many shapes and shades. Once the mob, for lack of a better term, decides to move it is very difficult to steer. And the mob is a mighty powerful force that has a tendency to sweep all before it, rational or otherwise.
People are not just rational beings, neither is the community. The 51% is dead, long live the 51%.
