Wow, I'm kind of back and forward on this. Part of me thinks he was right for doing so because he brought up a huge controversy to the American public, and part of me doesn't like him because he betrayed the nation. Honestly, the NSA is not really involved in our lives. They DO monitor our history, phone calls, texts, etc, but it's for a good reason. They want to help catch terrorist/murders/criminals. If it wasn't for them monitoring us, literally THOUSANDS of these people would probably be still walking around today. I think that's the fact that people overlook a lot.
The government also set up laws to make sure that they can't specifically peruse a person just for no reason. So, even though they have all your records and things like that they have to prove they actually have reasonable clause for looking through it before they do.
A LOT of people do things in the dark and don't want them to come to light. We all have sexted/watched porn/stole a song or movie on the internet at least once or twice, and I guess the idea of the government having that on file is a little bit nerve racking at best.
People hit that "clear browser history" button every day and try their best to pretend what just happened didn't happen. In a way, a kind of sympathize with people who hate the NSA because I can understand how nerve racking it can be to know that people can know the "real you" at anytime.
