People like Jake Appelbaum that manage (or actively try) to stay in the spotlight also educate the general public about security. That is something very valuable for a community: to have evangelists going around and spreading the word while getting all the attention. Just look at people like Noam Chomsky, Richard Dawkins, Jacob Bronowski, Carl Sagan, and so on. They could have all been doing science instead of working for months on television programs. They didn't because they believed educating the public is a worthwhile task. I sure hope we never run out of people that share the same opinion.
