This is my thought as well. The whole point of this system is that if you feel like you have better choices and ability, you are well within your rights to spin up your own instance and manage it, and make your own choices. Just follow the standards, and you should be able to integrate with existing platforms. They are free to defederate, but that's their call to do so. It's always been a tradeoff, and one of the big things with Reddit is that, even to a point now, it's Reddit or nothing. With federated sites, leaving a platform isn't starting completely over like it is leaving Reddit.
