If you had to convince folks that the fediverse / activitypub isn’t decentralization and all the perils of the former, what stories/anecdotes/tech arguments work best?

Imo federated systems address server-to-server decentralization - eg, whether a threads.net can talk to a threads.social server

But what users really want is not this, but to prevent threads.net from cancelling/bricking user.Me!

Blockhains provide such server-to-user decentralization, solving the actual user problem

building /bracket | talking /greatbooks | ex-BCG, ex-PHD | poli + phil + econ

there's always going to be the ability for an app to have to suppress a user (otherwise spam or bot protections wont work). i think the answer is those folks can then go to another spot?

isn't that possible still with the fediverse? for example if I go to another server (server A ) with my Threads.net profile/data and server A blocks me - I can still go to Server B with my threads.net profile/data

My knowledge on fediverse is on shaky grounds but I believe there is no underlying protocol (like farcaster) which stores all the messages. The servers store the messages for their particular set of users
