Yeah but unlike activity pub, atproto/bluesky demands each self hosted relay process a massive amount of data to participate, it is incredibly impractical and costly to envision scaling up, bluesky’s self hosting is essentially made to be a curiousity rich developers with access to powerful hardware try out as a hobbiest project and write a blog post about, not a serious general use case for everyone.
The idea of course is make it so nerds can technically do it, but the bulk of users can’t and won’t.
The strategy is convince the nerds you are giving them access to the future and that average people aren’t ready for it, and than never actually provide that future since nerds stop advocating for it because a corporation handed them a tiny scrap and that was enough to write a good techy diy blog post about.
Bluesky is the past desperately trying to convince you it is the future, don’t fall for it.
Here is a good blogpost about it

TL;DR Bluesky is not functionally federated nor decentralized, it is dubious if it ever will be and the layer of post sorting and moderation required to participate in Bluesky’s network is extremely computationally intensive and this aspect of Bluesky is NOT open source and is a proprietary black box.
The fediverse and activity pub are the future, even if the current hype train leaving the station (…who is paying for all the free drinks on that train and why?) makes it feel otherwise in the short term.
