pardon my ignorance, but how is a de-centralized and de-federated online community bound to such annoyances?
They're still a corporate entity, and they still want access to markets to make money.
i think i'm conflating lemmy with bluesky. can't anyone just host an instance? is it open-source? sorry, i should probably just look into this myself.
Claims of Bsky's federatedness and decentralizedness were greatly exaggerated.
I think Mastodon is closer to Lemmy as a Twitter alternative over Bluesky.
However, this does a good job explaining the differences:

thanks - you've got it. i forgot about mastadon. ironic, really, since it's the resource that everyone will be scrambling for in a few days. mark my words: something horrible is going to happen this weekend, and it will change your life forever.
What makes you think that? Genuinely curious.
Bluesky claims to support federation while being designed to make it entirely impractical and is currently entirely centralized.
For those who don't know, Bluesky isn't really federated. The only way to host a non-Bluesky instance required 1TB of storage in July 2024, and 5 TB of storage in Nov 2024. Could be way more than that now.
You basically have to be a company to federate into the ATProto (Bluesky) ecosystem. You can't just "stand up an instance".
Lots of detail: https://dustycloud.org/blog/how-decentralized-is-bluesky/
(I know you've already realized that you were conflating Mastodon with Bluesky, I'm putting this here for others who come along so they can get the facts).
5TB requires you to be a company??? My personal NAS already has 92TB
@egerlach @toy_boat_toy_boat Yeah, ATProto is a joke and it is surprising how many computer-toucher folks have fallen for it.
Also DMs always go through Bluesky themselves.
yeah the DM system is something completely exclusive to their official servers and that they just rolled up without caring at all about trying to keep up the pretense of wanting to build something decentralized.
That’s not an outlandish amount of storage. You can get more than that for $200.
At the rate it's growing, it's going to get outlandish very quickly.
Assuming you are serious:
Bluesky is ... arguably 'federated', but it is centralized, not decentralized.
https://gigazine.net/gsc_news/en/20241128-bluesky-decentralization
Their model (AT Protocol) relies on a central, authoritative ... 'Relay', that all 'federated' users and posts on federated PDS (personal data servers) must go through, to actually reach the 'AppView', ie, what all other people/users can actually see.
So, this is not a many to many, tangled spider web of connections, the way lemmy, and other parts of the actual fediverse are.
It is a top down hierarchy, a pyramid.
And Bluesky runs the Relay, the chokepoint.
If Bluesky cuts off the PDS your account is on, everyone on it is now gone.
The actual fediverse, Mastadon, Lemmy, etc, runs on ActivityPub.
In that model... every instance is essentially self contained, and every instance that is federated communicates with every other instance that is federated.
Each instance can decide what other instances they want to federate with... and users on each instance can personally block even more other users, communities, or entire instances if they choose to, but that only effects what that particular user sees.
That is what you call decentralized, approaching, or also having elements of being 'distributed'.
To bring up an example without getting into the drama that led to it:
The 'Tankie Triad' of ml, lemmygrad and hexbear have had a number of other instances defederate from them.
But, there are also a good number of instances that have not done so.
So that means if your account is on hexbear... you can't see or post on an instamce that has blocked your instance.
But, if you (a hexbear...ian?), post on a neutral instance... users on that neutral instance will see the post.
But but, if a user from an instance that has defederated from hexbear goes to to the neutral instance... they will not see the hexbearian's post.
This sounds complicated, and it is, but ... thats the whole point of a decentralized system. It is more complex in the abstract... but the entire system ends up being more robust, more adaptable, more customizable... without a central authority in direct control of the entire system.
Idk if you made those technical diagrams yourself but I genuinely enjoyed them.
"The fediverse is more like a big ball of wibbly-wobbly...timey-wimey...stuff."
This belongs in Best Of Lemmy or something.
I don't even know if such a community exists, or what instance(s) it would be on if it/they do exist... but uh... if one does somewhere, I guess you could submit it?
I am assuming it would follow the basic rule of ... you can't submit your own posts/comments lol.

i was asking in good faith, and i can't thank you enough for providing such a thorough and effective answer.
it almost sounds like bluesky is just a baby twitter in the making, and it'll probably end up the same way. i'm really digging the actual fediverse thing, mainly because it seems to be one of the only places that money and vc bs hasn't been able to touch.
You're right that Bluesky isn't federated, but it most definitely is centralized.
The answer it's, they're neither thing right now. And the claim has been made that in order to run your own instance that forwarded all traffic generated by the primary instance, you would need equivalent hardware to what BlueSky currently has. Vs Mastdon, which is…
