@marcusgreen maybe to build on something @dameoutlaw@mstdn.social was touching on:
An ax I grind is that the ActivityPub protocol and Fediverse were consciously designed to put instances, not users, at the center of the system.
Everything is controlled by instances, and the refrain of "Well a user can just set up their own instance!" only reinforces this.
The instance focus has all sorts of implications ranging from moderation through system performance, so it's no small deal.
I would much rather have had a focus on users, but that ship has sailed, and there's not much to do about it at this point.
