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 fact that things get divided up by the community itself is a positive, not a negative. The “major” network of instances don’t have to put up with extreme things on any end of the spectrum while those who do want to take part in that get their own bubble and won’t have to cry about censorship.
