This week, the Catholic Church wrote one of the better diagnoses of why decentralised social networks keep struggling.
…the collaboration between instances on things like moderation is virtually nonexistent. There is no form of federated diplomacy, or even a mental framework on how servers should interact, besides defederation when you get too annoyed with another server…
… [On the other hand, with BlueSky there is the opposite failure mode:] solidarity without subsidiarity is the benevolent provider of infrastructure: one big network that takes care of everyone and quietly removes their agency."
Well, the Pope in his encyclical is talking about the Catholic concept of Solidarity which has to do with the common experience of humanity and having works be for the benefit of all of humanity. It’s a much more broad and ecclesiastical than the strict definitional term.
Solidarity in this sense applied to the Fediverse would be more about how the fediverse connects people towards a common goal of communicstion. Bluesky doesn’t have solidarity as implied because it’s centralization isn’t solidarity. When it became popular, Twitter, in transmitting and aggregating short bits of data across the internet, did: the technology was agnostic to the content. That’s where there’s “solidarity” in Bluesky: as the idea and concept of Twitter now exists beyond both BS, X, TS, and so on.
Shared block lists and such though is just building another Catalogue of Abominations.
