Defederation is an important tool and is part of what makes the fediverse work. In my experience, people who are strongly defederation averse are mostly either quite new to the fediverse or have the relative privilege of never having to really deal with bad actors especially en masse.

The more the merrier for the Fediverse and if you don’t like it, join a smaller project or find one with the privacy policy that suites you. defederate

The good thing about decentralized platforms is that you don’t have to immediately cede the public square to corporate ownership or resign yourself to sharing space with the worst bad actors.
