> My issue with federation is that so far, everything still requires some centralisation. Take Matrix for instance. The most popular homeserver by a long, long shot is the one that the Matrix foundation runs themselves. This is same for Mastadon, PeerTube, etc. If you let this experiment play out long enough, you end up with a de facto centralised system.

Yeah this was Gagron's fault. Running a flagship instance was bound to result in this. I make it a point to educate people about not joining mastodon.social and finding another instance that better suits their interests.
