The whole point of the NSA is that it does the things that Snowden revealed. They were tremendously annoyed by it not because he revealed they were doing it in the abstract but because he revealed details that got people to change their practices, forced the NSA to change their practice, and reduced their effectiveness.

Some of those changes should have happened anyway. Snowden's revelations pushed people to use https ubiquitously. It doesn't just protect against NSA spying but other countries do stuff like that too as well as non state actors. (There was that time I switched on wireshark on WiFi for 5 minutes and was like damn... I've got a lot of email passwords.)

Like it or not, driving from DC to the airport in Baltimore you drive past the puzzle palace at Fort Mead and it's got a huge parking lot and one of the worst traffic jams in America when the quitting bell rings at the end of the work day. If they weren't spying on people but instead spending the money on ski chalets or beautifying the inner city or something, that would be a real scandal.
