With that given said, compare a whistleblower, say 20 years ago, with one today. Snowden not only had the world's greatest communication platform at his disposal, to disseminate whatever information he cared about, but now he can still address millions of people, speaking at the world's greatest universities and giving interviews, while being in exile.
Regardless on where you stand on these privacy/spying issues, I think it's hard to deny the fact that he started a dialog, and now the entire world can be part of it.
