Right now I'm watching this video (
and just learned that a ethereum contract can be killed by its author (starting at 30:50)). But doesn't that mean that he has in a way full control over it? Lets say I make a smart property dapp, and a lot if people manage their property with this dapp. Then I sell my property, get the reward (bitcoin or whatever) and then I decide to destroy that information by killing the dapp. This would mean I totally need to trust the author of the dapp to not kill it. Is that right? Or am I getting something wrong?
