Federation isn't the same as "practically the same server". That's just Twitter or Reddit you're describing then, a single fully unified pot of information that is still spread out over a vast amount of individual servers for only for parallelization and redundancy reasons.

Federated applications like Lemmy are, as the name implies, federated. Not merged or unified or so.

E-mail is also a federated protocol. Imagine if every time you wanted to send an e-mail, you had to check whether your provider likes the recipient’s provider and if not, create an account at the recipient’s provider (if that’s even possible).

Oh you mean like that thing email servers do when they block other email servers. Yeah imagine that. That'd be wild! 😂

Yeah, I know that and how the same people who support defederation love to complain about Gmail and Outlook blocking their home server.
