Great explanation of Bluesky’s current technical status by @cwebber@social.coop (a long technical read): https://social.coop/@cwebber/113527462572885698
Summary: @bluesky_social has incredible potential, but they are misleading users about being decentralized. They are, however, the perfect Twitter/X alternative.
Also, running a PDS (Personal Data Server) is expensive, which can range anywhere from $200 per month to thousands per month). [参照]
If Bluesky embraces true decentralization (they are still technically centralized right now), it will be expensive for anyone to run their own PDS & relays, which will make Authenticated Protocol Transfer (ATProto) more for the affluent & not for the commoner.
A person can run their own ActivityPub instance for around $6/month—& that is for managed hosting (you could reduce the price further if you have the technical skills).
So in the end, if all you are looking for is a Twitter/X replacement, then you should use @bluesky_social as it is designed to be a Twitter replacement.
However, if decentralized social communication is your goal, then the ActivityPub / fediverse is for you.

The author doesn't say that PDSes are expensive. They even admit that PDSes are cheap:

What they say is expensive is "relays" and "AppViews", akin to Google Reader, whose cost grow in proportion as the entire Bluesky network grows. And the problem is that Bluesky as social media utilizes an architecture the author calls "shared heap" that heavily relies on them.
