You obviously have never been to the Fediverse, nor done any real research into it. This is not "the same exact people running the same exact platforms for the same exact reasons." It's the Fediverse, not BlueSky. I also take it that you're too young to remember user forums of the web 1.0 epoc, where instances were run by unpaid volunteers for years, or the even older dial-up BBSes that did basically this same ("Fediverse") thing back before the Internet explosion.
What they're "pitching" is what the Fediverse is: small(ish) instances run by unpaid volunteers who have accepted responsibility on their instance. For example, let's say you sign up with InstanceA, because you want to see what this Fediverse thing is about. First off, unless you browse "all", you will only see the account(s) you subscribe to. If you don't like how 'forumX' has devolved into verbal fisticuffs, you can ignore (called "block" in most software) that forum and never see it again. If InstanceX is spewing nothing but hate, the admins of InstanceA can 'de-federate' with it, which means you as a user of InstanceA will never see anything from InstanceX again. More recent versions of Fediverse software let the user block the whole instance for themselves but not other users of that instance. From what I've seen, most Fediverse clients allow you to block users, forums, and whole instances.
The Fediverse is mostly the descendant of those user forums, where now you don't have to sign up for that instance to see their forum(s), your instance talks to theirs and ships messages back and forth so you can still browse and post to "mrbig@mastodon.xyz" or "I-heart-cats@catsarecool.xyz" from your instance, rather than signing up for the instance "mastodon.xyz" or "catsarecool.xyz" to see that forum.
What you're "pitching" is basically Facebook/Instagram/TikTok TNG where users are still subjected to whatever random bullshit "the algorithm" promotes and "moderation" is a half-baked attempt to keep people from drowning in the drek that comes up. No Fediverse instance I've ever used or know about does anything even remotely like it. Honestly it's kinda the opposite, where if you don't browse "all" you will likely get bored with all the accounts/forums you've subscribed too because all they do is run user posts (Some unfiltered, some filtered by the group admin(s)).
For the rest of us, who have actually used the Fediverse, rather than just pontificated about it online, the real question is "how is this going to work long-term", because just like the old user forums and BBSes, without a financial incentive, a lot of this will go away when the volunteer admins and mods die or wander off.
