The thing a lot of people dont seem to get about centralization is that it’s much more a social phenomenon than a technical or corporate one.

Things will eventually gravitate towards a handful of big instances. People want to be where other people are.

The difference will be the federation. As long as everything stays federated, this won’t be a problem.

Except…once an instance gains dominance, defederation becomes a defacto way for that instance to declare what is and isn’t worthy of visibility.

Defederation absue by large instances is going to be a much bigger issue than centralization.
