A lot of people seem to have difficulty with that.
Edit: we need better privacy laws and transparency around a lot of things, that said, some state actors are going to need to be around for a long while yet. It's a complicated world, none of this is black and white, it's why we need vigilance.
As the other commenter said, the crimes the NSA did/still does far outweight any "crimes" Snowden did. And whistleblowing is by definition illegal since you have to release confidential files. That's why functioning countries should have laws protecting whistleblowers.
I find it very strange that so many people are more exercised by the small crime of Snowden releasing this information than by the large crime of the federal government spying on us all.
