I found myself chatting with my dad and brought up the topic. I couldn’t come up with any actual advantages a federated platforms had. The main reason I use any federated platforms is because they’re either not as enshittified as the alternatives or run by huge dickwads. Since it mostly fits those criteria, I’m on Bluesky too, but once that goes I’ll either switch to another un-shittified platform or Mastodon.
But on its own, what advantage does a federated social media have?
Mostly just the resilience and control. An outage or censorship incident on one node can be contained, isolated, and users can easily go around it.
“Oh no, my preferred instance went down!” switches to another instance with the exact same content
Also, I think some European governments run Mastodon servers for themselves. Which sounds weird, but makes more sense in an IT security context. Their data, stored on their servers, that they manage. No third party business contractors needed.
