This is the counter example to "protocols and interop solve enshittification". No, they don't. Email is the model protocol: perfectly interoperable, perfectly decentralizable. And yet it is centralizing in the hands of a few organizations who then wield enough market power to bend everyone else to their will. It's still enshittifying. If email hasn't resisted enshittification, then interoperable protocols are not the solution for it. And yet, pretty much all of the pro-social, anti-enshittification effort in tech is being directed into protocols and interop.
