Bsky offers an on-ramp to a more decentralized experience, but most people won't pay the money and experience the friction to move take that ramp. Platforms like Mastodon are entirely decentralized, but that means the friction of decentralizing happens immediately upon sign-up. The people who don't want to self-host PDSes never signed up for Mastodon to begin with.
I try to be skeptical, but I feel like bsky (or something like it) is the best way can do re: bringing decentralization to the masses.
If there's nothing stopping anyone from fixing a problem, and yet nobody fixes it, then there's something is stopping them.
Might not be a technical impossibility, or a gun in their head. Could be as simple as inertia or addiction.
But saying "the problem is totally solvable" just because there's a solution available, is pretty naive. Solutions have costs themselves, and not all are created equal or equally feasible.
Also, the open source version of the appview doesn't work at Bluesky scale. You need a proprietary database for sufficient speed.
AT Proto is completely decentralised, except for all the structural and financial points of absolute centralisation.
The work towards permissioned data and group-shared data will make it so apps can choose their own levels of "decentralization" of "federation" on atproto primitives. For example, two diametric options
1. An app that is not open source code, but still does all the same atproto credible exit stuff. Naturally leans into winner-take-all
2. An app that is tied to community, think something like Discord, where most servers don't care about what other servers are doing. Each community could run their own version and only care about their data. This is raspberry pi hostable.
Maybe there are a ton of people who joined Bluesky because twitter devolved into a room-temperature-IQ right-wing hell hole, not because they cared about federation or whatever.
Everything has trade-offs. Again and again people choose centralized services because they are a better product.
I'll be the first to admit I'm guilty of this, too, and still haven't gotten around to moving my main account to a self-hosted PDS (though I've at least taken the steps to backup my CAR and set my own rotation keys, such that if my PDS goes offline or hostile I can still migrate away from it).
Is there something missing from my answer about what the plan is for the PLC?
