I can clarify. My point is that the code on the ethereum main net is immutable and permanent. If it wasn't this guy, it would have been someone else, either malicious or not. If you deploy code to the ethereum main net, it is vulnerable to the world. The issue isn't that the guy was toying with main net contracts, the issue was that the contract was busted, and there was this room for problems. Ethereum has been extraordinarily prone to these sorts of errors so far (see the DAO). As of now, the foundation is unstable and the stakes are high.
