Guy discloses vulnerability. Facebook is not as impressed as guy would have hoped. Maybe it&#x27;s because he&#x27;s one of several people to disclose the same vulnerability. Maybe there are just a lot of vulnerabilities (they&#x27;ve paid out 4.3m in bounties).<p>Guy&#x27;s reaction to rejection: take hostages and threaten Facebook. Facebook moves to defense and cuts guy off.<p>You are not a good neighbor for kidnapping someone&#x27;s family to prove to someone their busted lock is a big deal. You show them their lock is busted and trust they can figure out what harm that could lead to. The alternative is companies being hostile to people just looking around their locks, which is the world in the 1990&#x27;s and 2000&#x27;s that responsible researchers are trying to avoid going back to.
