My own take on this is that Ethereum was meant to counter this tendency by those who own servers to control, manipulate, or even hack one’s personal data stored in any existing server. It aims to curtail or disrupt third parties that may be storing vast amounts of data in a way that centralizes the whole internet thing. But the question remains: how sure can we be that the structures or “nodes” created by Ethereum will not be in a position to do the same thing that was being done by the previous “centralized” system they replaced?
