I hope your smiley meant you are joking, but the wording lets me doubt it. Don't confuse immoral with illegal.

What Snowden did was in no way immoral. He exposed the wrongdoings of the NSA. The case with Wikileaks is similar.
These people are heroes, they sacrifice, or at least risk, their personal freedom just for the chance to stop these wrongdoings.

Its like saying a guy who exposes a group of human traffickers acted immorally because he exposed his working colleagues.
