I hope people know that us all having instances would always be better than anything centralized elsewhere. 1) I can delete all my posts if I want. 2) anyone can make a better app to talk to it. 3) we got so many different ways of sharing our free speech here, it's not even funny. 4) you can backup your stuff. I'm not, but you can do that if you serve your own server. 5) you can establish your own rules or land on someone else's server that you trust.
At this point you gotta be a lower form of life to conclude that going centralized is good for anyone.
