He’s hardly a naive whistleblower. A whistleblower encounters something inappropriate in the context of doing his job. Snowden sought the employment specifically to snoop.
He positioned himself as “watcher of the watchmen”. Who’s watching him?
Thank God someone was willing to put himself in a position to expose this stuff. Why should anyone watch him? News flash, we don’t need a government watching over our every move like the east German Stasi. The government should be afraid of its people, the people shouldn’t be afraid of their government.
