If the descentralization of social networks continue, we will have to prepare for the eventual rise of the instances wars, where people will start to fight about which instance is better and which one is weird to be in and so on, but that’s for the future of us all.
The 2nd largest instance has already de-federated themselves to create a walled garden with reddit-style moderation, eg you can be banned because the mods don’t like what you said, even if it does not break the rules. That instance is: beehaw.
