I completely agree with you—the large exodus from Twitter means that both sites have the Twitter feel, so people can choose. My point about decentralization is that it imposes some weird technical limits on Bluesky for reasons that the normal users it is now attracting have zero interest in. For example, the list of who you block is public, and you can't quietly make someone stop following you by quickly blocking and unblocking them. I'm sure there are additional limitations, too. All of these stem from highly religious architectural choices that are of no interest to 99% of the current user base, who just want pre-Musk Twitter back. The obvious endpoint is what happened to email—there will be one central provider who can set arbitrary policy, and the decentralization part will just linger on as a series of annoying hoops that developers have to jump through to work with the de facto centralized site.
