No one really considers crypto held in exchanges as decentralized, I guess some might but it's pretty standard knowledge.

We're talking about Binance, a centralized exchange.

it was all a lie

I keep saying this: don't bother trying to dunk on crypto people with accusations like this. To a first approximation, nobody in crypto actually believes in the stated principles of anti-centralization, freedom, etc. It's entirely about number go up and always has been. Your charge of hypocrisy just bounces straight off people who never cared about the politics.
