That’s a con and a pro of decentralized net: if you don’t like the owner, pick another instance or create your own and be the king. Bad news is, every instance is controlled by couple regular folks who’re not responsible financially so they can imply their own rules and post and ban whatever they want.
Like the jungle: you gotta learn to survive and avoid the monkeys with rabies.
Always love blaming the tool instead of the hands that use it
