I think complete or pure decentralization is almost impossible to achieve and yeah, we can see this on Hive. Even folks with governance rights will treat the right like a privilege or some sort of authority, rather than a right to governance according to what people on the blockchain wants.
If people who are put in charge don't see themselves as servants or folks who are delegated the right to lead, it'll be definitely difficult for things like decentralization to truly work. This is a major problem when true decentralization is being attempted
