Lot of arguments against Mastodon can be boiled down to : "But I really want a big centralized power that tells me the centralized truth".
Decentralization is hard because there’s not one single objective truth anymore. There’s no more one single way of doing it. There’s not a "good" answer to your question. There’s no official scale of worthiness.
You need to make mistakes, to be frustrated, to discover unwanted things.
You need to (re)learn to be a human.
It’s hard and political.
