Yeah, "go away if you're not happy" is really the lamest answer possible. And he is more like "captain reddit", always freaking out about popularity and subscribers.
Kbin.social is the official flagship instance representing kbin, and should strive to remain above squabbling over politics, only defederating from instances that are actively harmful.
Lemmy.ml is so far not an actively harmful instance. Plus, most people on kbin would prefer not to be defederated against their will and be unable to subscribe to communities from there.
Appeasing to "most people" would be more of a "democracy" (majority rule) than a "fiefdom".
It actually might be a good idea to organize some votes in the platform to decide on things like this.
