As I see it the only advantage is that it is not run by Elon Musk.
And by 'advantage' I mean the 'advantage' of using a corporate product that, so far, is doing its best to drive people away from an actually censorship resistant Fediverse, using inclusive rainbow capitalist language to lure in the large majority of people who are not tech savvy enough to realize they are basically lying to / misleading them.
That is literally how I read it as well, BlueSky is farming out server load to enthusiastic and dedicated users, while also just going ham on the PR / propoganda / marketing making themselves appear to be something they are not.
Unless I missed something and BlueSky is actually letting people run and custom configure their own relays at least semi independently... yeah, they're basically being quite shady and misleading.
I was oversimplifying a bit such that it wouldn't be overwhelming to a self-described uninformed person asking for an explanation.
Yes, there are multiple actual relays but they functionally constitute a single layer or class of components in a birds eye view of the whole system.
As far as I am aware, no one other than BlueSky runs the relays, or has the code to do so.
If I am wrong about that, I would appreciate a source indicating such.
Does anyone other than BlueSky actually run a relay?
A kid in my apartment building was walking down the hall, taking his dog out for a walk... just singing 'What the fox say -ring ding ding ding ding da ding da ding.'

On the bright side, at least our upcoming American cyberpunk dystopia is now more likely to feature a greater prevelance of lone wolf, broke, two bit hackers as a semi-viable lifestyle/'career path'...

I am sure if you ask them, they will blame it on water flouridation.

Oh right, of course, I almost forgot: Someone in my family got the covid vaccine and the vaccine shedded and gave me spike proteinitis!
Oh how I wish the X-33 / VentureStar had actually worked out...

Either something like that, or somekind of... craft that has both a RAMJet and also some kind of rocket propulsion... that or a SCRAMJet that actually works... could maybe help get us to, or toward, at least an SSTO craft, or system.
Hah, or we can go full conspiracy theorist and find and publicize the anti gravity field generator equipped TR 3B in Hangar 18 or whatever, haha.
Play Kerbal Space Program Realism Overhaul if you want a ... much closer to 'real' taste of how much more complicated and difficult an orbital flight is than a subortial flight, a lunar flight is than an orbital flight, an extraplanetary flight is than a lunar flight.
I'm not sure if it is still the unofficial motto of the mod... but it used to be 'if you cannot figure out how to install this mod, you will not be capable of playing it anyway', or something to that effect.
My experience as a person who has a lot of experience working with computer is basically thus:
When you solve a problem for someone, you are a magician.
When you can't, you are completely full of shit and know nothing about tech and your entire life is a lie.
When you tell someone 'hey I wouldn't do that', your experience and expertise means nothing if what you are suggesting would mildly inconvenience them for 10 minutes, or takes more than 30 seconds to explain why it is a bad idea.
When you tell them 'hey have you tried this?' your experience and expertise also means nothing if you cannot do it for them and also make it so it never breaks again, and also they will keep doing the thing that makes it break even though you explained to them how to not do that thing that makes it break.
... I may as well just start an IT flavored Rodney Dangerfield comedy routine, it would be much more fun and less stressful than always being a db admin/data analyst/backend dev/frontend dev/whatever else my job title now apparently includes.
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.
Like a toilet bowl, mounted to the ceiling.
