You may hate the NSA, but I’ll bet you like that terror attacks on U.S. soil are very rare things.
This may surprise you, or not, but there are actually quite a few people in the world who would like to change that.
In real world, the protections of the Constitution do apply only to Americans, and if you use our infrastructure and technology and inventions to plan attacks against the citizens of this country, well, it would be silly for us not to know about it.
Have you seen “The Imitation Game”?
Edward Snowden would be like a low-level clerk at Bletchley Park who saw the de-cryption device, realized they were listening to RADIO signals…just like the English used…and while all everyone at the NSA cared about was German codes, the device also gave the ability to listen to local radio signals…and oh my god he had to tell the papers…which also alerted the Germans that all their codes were hacked.
That’s who Snowden is.
That’s why he’s a traitor (and currently taking refuge in a country we are all but at war with).
