You’re way too aggressive about this. You can join any other instance and access the same content, or start your own. Nobody is “silencing” you.

If you want absolute control over what instances you’re federated with, start your own instance. Otherwise, find one that’s more closely aligned to your views.

As others have said, this is one of the main points of federated networks, if you don’t like how an instance is run, you can take your ball and go play somewhere else.
