One issue for me, and this is also true of Mastodon and by extension Mbin, is that I greatly prefer the voting and focus on a topic area rather than person. X / Twitter / Mastodon / Bluesky is where celebrities go to increase their profits, fame, and relevance, while Reddit / Lemmy / PieFed (/ + nodeBB + flarum + others) are where we discuss matters of import. I'm not criticizing your post here - this is definitely the correct community to discuss such matters:-) - just interjecting my personal preferences into the conversation, to disclose my own biases.
If Lemmy.World went away, then correct you would not "lose" the users as, well you said it, they would simply move to another instance.
But if Lemmy.World remained and you blocked it (if you had a method to do that - it's not easy at all using base Lemmy but it is doable with some older apps or like Ublock Origin filter rules and such), then in that context you would indeed "lose" all of that content. Or like if you got banned from that instance then that's another way that you could "lose" access to engage with communities located on it.
The more centralized something is, like Reddit, the more damaging it is to lose access to it, while the more decentralized, as you pointed out, the less overall effect that perturbations have upon the network.
The next issue then becomes cost. Which affects Lemmy as well: first there is the requisite effort to set up and self-host even a tiny instance (especially as it relates to potential spam and CSAM attacks), and second the network traffic costs. The latter may be tiny for a single user who only subscribes to a handful of communities, but someone trying to browse All and wanting everything to be available for their perusal (even if deleted soon-ish for storage reasons) will bear a much higher burden. Which depending on local costs may be trivially easy... or prohibitively expensive, but in either case the more data that someone wants to pull in the higher the cost.
And I imagine that Bluesky is either similar, or significantly worse.
Looking at your other comment on this thread, thank you - that kind of breakdown was precisely what I was hoping to see!:-)
So Bluesky is more decentralized than Reddit (or Facebook), but barely, and far less so than any Fediverse platform currently.
I think what OP was trying to convey was less the current state of affairs and more the underlying protocol itself, which they re-released now under a separate post.
There is no hope anymore... of avoiding consequences entirely, or perhaps in minimizing them. There IS hope that humanity may not go extinct. The trick as I see it may be to find the balance in between those extremes:-). (Unfortunately I don't know where precisely that is.)
Edit: people downvoting, please speak up why you believe this is wrong, and if possible send me a link to read in order to learn more? (I tried to include one in my comment but went down a rabbit hole and gave up, with lemm.ee going down I can't find what I was looking for.)
I hope I am not adding to the problem here as well. It seems that obviously Bluesky is neither fully centralized nor fully decentralized. Is there a statement about just how much of either it is?
Although that might be complicated - like someone could say that Lemmy is fairly centralized, bc if you block Lemmy.World then you lose half the users and perhaps half the communities (and PieFed even more so, with PieFed.social representing an even higher fraction of users and communities on it).
So there is a distinction between Bluesky the service as it currently is implemented and Bluesky the protocol, the former of which is fairly centralized but the latter is more expandable?
Normal human ways of thinking go like: however you do it, so long as the job gets done it's fine! โบ๏ธ
PM thinking: even if nothing ever gets done, so long as I collect a salary we continue to have 3 hours of meetings most days every week, it's all good! ๐ค๐คฏ
Also, afaik, the conflict between the PO and PM roles is somehow literally the point? You get blamed if the tasks don't get done, while the PM ensures that endless reports get generated - I doubt the vast most of which are ever read, and I know that I for one can never find one of those later, in part bc there are so many of them and they encompass everything else into them as well (Jira tickets, Slack messages, hundreds of emails per day mostly saying "this Jira ticket or that Confluence page has been edited", the former of which for the life of me I cannot figure out how to turn off!).
So... not only I but we all feel your pain! Otoh, that seems one of the first job roles that will soon be replaced by AI?
Be careful!
