Something can be decentralized and non-CEO-proof at the same time. Cryptocurrency and related technologies are decentralized, but the wealth and power imbalance between the "peasants" and the rich-get-richer "nobles (derogatory)" is massive (see: 3AC, Celsius, Terra/Luna, etc).

Compare that to the fediverse - if an instance gets spezzed up by some CEO-minded knobhead with bigger ideas than brains, that instance can be defederated. It would still be a great loss of content, but it is decentralized in such a way that one person can't take down the entire ecosystem.

P.s. "spez" is now a verb, it means "to have a passable product/service completely fucked up and its users turned against you because you wanted more money".
