It's one of those things where the very tankies you're talking about made it trivial for anyone not wanting to interact with them, their instance, or anyone in specific can just block whatever. And then there's the instances that defederate from .ml and/or grad, which is a decent amount of them.
They may be assholes (though they tend not to be in interpersonal ways, only in their political views), but they're assholes nobody has to interact with for very long.
