Oh yeah, no, it's very centralized at the moment and even in a perfect implementation it'd still be somewhat more centralized than Nostr. Still, they've made a lot of progress (going from 100% centralized to mostly centralized in a couple months earlier this year). Theoretically, whether you were having X.com or Y.com aggregate data from PDSs, it'd still be the same PDSs so people from X.com could talk with Y.com - assuming no blocking/errors/funny-buisness was going on.
And for the DIDs, you can actually hold your own with your own PDS. Bluesky itself won't hand you your keys yet, although they are planning migrations at some point so they likely will in the future once that side of thing is developed. Probably not ideal for us and our fellow tech nerds, though most people probably won't care or even prefer custodially held keys.

The point is that x.com and y.com have the power to block each other's accounts. So as I say, there's no point setting up y.com. It's much cheaper and easier to set up an AP server or Nostr relay instead. So unless something radically changes in the ID layer of ATProto, it will always be controlled by BlueSky, and it will always be as centralised as Xitter where it matters most.

This is like when apologists for Gmail say that most people don't care about runing their own email server. Or when apologists for proprietary software say that most people don't care about reading or modifying source code. Or when apologists for dictatorship say that most people don't care about reading laws or government reports.
It's probably true, but entirely beside the point. The fact that you *can* do it, if you want to, totally transforms the incentive structures.
