So you find a vulnerability in the internet operating system routing the vast majority of the internet. You bring the news to your boss; You bring the news to the maker of the routers. Do you give them time to repair it? No of course not, instead you throw your job away so you can blab to the next gathering of black hats giving them all the juicy details so that if say, a fourteen year old who has a beef with his girlfriend and his buddies decide the best way to get back at the world would be to say, take down a couple nodes (read: PoP) on the internet -- yeah, that'd be cool -- then maybe we could all grow up and get lives and realize that loose lips do sink ships or in this case, networks.
