The other day I was thinking bitcoin itself is decentralized, but everything around it is centralized or striving towards being centralized. Let's just take a look at this forum for example. Here are certain people in such power that if they decide, they can destroy you - your forum nickname. Members with trust can give you negative trust for no reason and you have no way to fight against that. Admins can ban you with no reason. Isn't that the principle of "centralization" - a few people having power to do anything and with no justified reasons?
