Did anything change in terms of policies or people responsible seeing criminal charges as a result of these findings?

I hate to be so cynical, but among people who are concerned about privacy and american influence, these findings are sort of like "no surpise the military surveillance state that built the internet for military and surveillance purposes would continue using it for military and surveillance purposes." I mean after all, many of us grew up getting threatening letters from the powers that be saying "hey, we surveilled your network traffic on behalf of the private moneyed interests who own all the IP in this country and found illegal activity." Witch hunts like McCarthy going after communists are public record and known parts of our history. MKultra. COINTELPRO. FBI writing a letter to MLK asking him to kill himself. CIA selling crack. Lying about Vietnam. Lying about Iraq WMDs. This has always been a bit of a banana republic.
