Could overlap a "Political / News" forum topic, but I was never surprised by any of the "NSA revelations." I still regard Snowden -- technically -- as a criminal, and I argue that his single-handed actions might not have occurred but for the willy-nilly outsourcing of what had once been purely-governmental national security apparatus. Daniel Elsberg took a different path with "Pentagon Papers" but Elsberg defends Snowden.
This all arose from the creation of NSA around 1953. The telecommunications industry evolved along with it. Read some history of the agency like Bamford's "Puzzle Palace" or "Body of Secrets." There are the "employees" at the Fort Meade facility, but there are additional "assets" -- I think some 90,000 people when Bamford's "Body" book was published around 1999 -- scattered across the landscape. They even have their own "para-military" as dramatized in the 1993 film "Sneakers."
Around 1997, I came across the web-site in Germany of a distant relative. I say "distant," because the last name is singular: there were only 185 of us in the US in 1985 per SSA records, despite having come to these shores in 1850. The German was a "microwave" enthusiast and expert; had a very innovative web-site.
He was adamant that e-mail communication should use PGP encryption, and I obliged. He never explained why, but I pretty much deduced it: NSA didn't limit its snooping in foreign countries.
Around 1999, BBC produced a documentary outing what they knew about NSA's ECHELON system, which had been under development since the early 1980s. This soon morphed into something else, as FIOS and wireless gained ground.
And in that BBC production, it was clear that NSA could tap just about any telephone in the modern world.
All of this arose with the National Security Act of 1947 and the Cold War. By comparison, I can't speak for the chicken-littles who reacted to the Snowden affair, but I met a 20-something young woman a few years ago while having my SUV smogged, and somehow some topic involving Robert McNamara came up -- a name she didn't recognize. I mentioned the "Cold War." She responded, saying she learned about that in high-school history class:
"Oh, yeah . . . . we were fighting the Columnists," she said.
None of this eclipses the real issues, but I wasn't much surprised with the frenzy following the Snowden affair, either.
