I went out drinking once in DC with some people who worked at the NSA in 2005 or so and they said they were hiring for people to analyze "all the traffic on the internet".

When the Snowden leaks came out it was not a surprise. Granted most people don't go out drinking with the people doing the spying, but even people who work at the NSA can't keep a secret, if it was even meant to be a secret.
