Signal relies on centralized servers that are maintained by Signal Messenger. In addition to routing Signal’s messages, the servers also facilitate the discovery of contacts who are also registered Signal users and the automatic exchange of users’ public keys. […]
One of the controversial things we did with Signal early on was to build it as an unfederated service. Nothing about any of the protocols we’ve developed requires centralization; it’s entirely possible to build a federated Signal Protocol-based messenger, but I no longer believe that it is possible to build a competitive federated messenger at all. […] [interoperable protocols] [have] taken us pretty far, but it’s undeniable that once you federate your protocol, it becomes very difficult to make changes. And right now, at the application level, things that stand still don’t fare very well in a world where the ecosystem is moving. […] Early on, I thought we’d federate Signal once its velocity had subsided. Now I realize that things will probably never slow down, and if anything the velocity of the entire landscape seems to be steadily increasing.

An open source infrastructure for a centralized network now provides almost the same level of control as federated protocols, without giving up the ability to adapt. If a centralized provider with an open source infrastructure ever makes horrible changes, those that disagree have the software they need to run their own alternative instead. It may not be as beautiful as federation, but at this point it seems that it will have to do.

The fact that we have a telephone system that works with separate providers contradicts this sentiment. If I want to pick up the phone and talk to my cousin’s puppy in New Zealand, I can do that without creating an account on his provider’s service.
I don’t understand why we’ve forgotten this as a society. Yes, it was difficult to upgrade the phone systems over the past century, but it’s worth it in my opinion. I really wish we’d start seeing government regulation that says “you should be able to talk to someone on a service without having to create an account on said service.” I thought the DMA would do this, but sadly, Whatsapp still requires an account to talk to people using that service. Very disappointing.
As for interoperability between services… Monetization of surveillance data. The social media companies are Ad companies, and they make their money surveilling people and selling access. It’s harder to build an accurate model of a person when only pieces of data is available, and they need to have more data then the other Ad tech companies they’re competing with.
Matrix servers keep a copy of any remote room an account on the server has joined, and it’s possible to recreate a room from the copies held on different servers. There are more details I don’t remember, but at a high level that’s how it’s distributed.
Storing messages of remote rooms in addition to local rooms is why people complain about the storage requirements of Matrix servers. They don’t realize it’s distributed.
Signal isn’t federated [1][2][3.1]; it’s decentralized [1][2][3.2]. Though, for all practical purposes, I would generally argue that it’s centralized.

How is the puppy?

Yeah, Moxie has openly shot down the idea of adding federation to Signal, and I’ve never heard them claim Signal was decentralized.
Matrix is federated, distributed, and decentralized.
XMPP is federated and decentralized.
It is? How so?

Interesting — I hadn’t considered it that way.
