But...
NSA, GCHQ, BSI/BND, etc. aren't the "bad guy" in theory.
It's within a nation's interest to, within the extent of law and respect for human rights, try as thoroughly has it can to know what's going on in the world. Electronic intelligence is part of that, and a growing part.
In practice, the permissive reactions many/most/all governments have to allegations (or proof) that a comms intel agency has broken the law, that's what the trouble is. That these groups have been allowed to break the law or ghostwrite laws that allow them to violate what would generally not be approved by a citizenry, that needs to be addressed.
I'm not sure how ruining the careers of software developers and computer scientists who've worked for these organizations does anything other than remove from circulation some brilliant members of our community.
Ostracize the middle managers, bureaucrats, politicians that allow the trampling of our rights.
But don't arrest the guy designing the home theater system for El Chapo's vacation house and tell me you've taken down the Mexican drug cartel.
