> Sure, much like how email is decentralized in theory but barely is in practice.
Hard disagree. Email is very much decentralized. Doesn't mean that there's still a long tail distrubtion, but its not like 99.999% of email accounts are on Gmail. And I can set up an email account in a few minutes and by choosing from a list of thousands of providers all over the world.
It looks like about 97% of people use iCloud, Gmail, or Outlook as their provider. That doesn't feel like it's terribly different. The people not using one of those big three make up a comparable percent of the total as the number of Bluesky users using alternative PDSes.
Three providers vs one provider does feel very different if those are the only option, but that's not the case for email or Bluesky/AT proto.

You can also set up an account on a different PDS and/or use a different app view quite trivially too so I'm not sure that's substantially different.
