It's like federating, but not.
Thanks for coming to my TED Talk.
I jest.
A lot of people compare the fediverse to email domains. bob@outlook.com can talk to sally@gmail.com - no issues.
Imagine if there was an email service made by Jeffrey Epstein, for him and his buddies; LolitaMail.
It should go without saying every email service should block all LolitaMail communications.
That's what defederating is.
I thought federalization was about not having an owner of a platform. Decentralization. I have some reading to do
The federation is community owned (which is why you see so many communists here).
Lemmy itself is not a single instance, it's merely the technical development of the platform itself.
You are a user of the sh.itjust.works domain, who is owned by a real person.
There are bad Lemmy instances you don't want to be part of, and the owner of sh.itjust.works has blocked that instance, you'll never even know it was there.
There is no single author of a list of instances which are defederared, but many instances simply piggyback off the blocklist another instance uses (lemmy.world for example).
not really, every Lemmy instance has an owner...
What federation is is that every Lemmy instance gets some of its data not just from its users, but also from other Lemmy instances. You can think of each Lemmy instance as one mini-reddit, in principle there is no difference between reddit and one single Lemmy instance. Federation means that Lemmy instances copy their data from/to each other so that you can talk to users who use other ones too.
So defederation just means we block some of instances
Ah so it’s about moving away from Lemmy and back to Reddit for example?
