The beauty of The DAO was that it wasn't even a hack or an attack. It was merely somebody cleverly exploiting a loophole in the contract everybody agreed to. After all in crypto-utopia "Code Is Law" and there is no interpretation of a contract outside of the code. The irony is the only actual theft that occurred was the ethereum devs rolling back the contract to save their own asses.
The DAO single handedly proved that the blockchain is fully mutable and is certainly not trustless or censorship resistant. Hanging your hat on any blockchain requires you to trust the developers and miners to do you well. And if they don't... good luck getting your voice heard.
Wasn't the DAO rolled back?
