>Ok, so what? Let those people block you then, sounds like people you probably don't want to interact with anyways?

The problem is when this is a large server with people you know using it. They suddenly disappear from your feed. And those people may not have even agreed with the reason for defederation.

At that point, the only way to connect with your friend(s) is for you or them to find new servers that haven't (yet) gotten into a defederation slap fight.

The TL;DR of the problem with Mastodon is that you basically need to pin your identity to what is essentially a small internet community/forum and then give them full power to decide who/what you can consume while your identity is tagged to their community.
