@thomasfuchs fascinating! And I take your point and you’re probably right!
There are most likely a few of these “centralising forces” lying around pulling people into mastodon.social, and not without good reason right? Without post mobility, why not optimise for longevity!
Another force I imagine is maximising reach and minimising defed drama.
Whether you dislike a centralised fediverse, it’s important I think to recognise they emerge from its structure and dynamics.
