Blue Security's CEO is quoted in the article: "It's clear to us that [quitting] would be the only thing to prevent a full-scale cyber-war that we just don't have the authority to start," Reshef said. "Our users never signed up for this kind of thing." You have to wonder where it goes from here. It seems an effective method has been found but more than a small private company could handle. Will someone else adapt this concept, or does the internet world give up?"
