from what i understand, a decentralized bluesky is nothing for an enduser at all.

TL;DR: the cost for an enduser to run a bluesky instance will soon be prohibitive because of the amount of storage needed owed to its shared heap architecture. but what it does is to provide a “credible exit” - if users lose trust or the company shutters, there’s nothing in the way of another organisation picking up the mantle and continue from there on.
