The ops are classified so it's a bogus point anyway. You're requiring them to commit a felony to prove specific damage. Further, you've already dismissed anything coming from spy agencies as a lie. You've set that line of questioning up to be a fail no matter what they show you. The only exception I'm seeing is a 3rd party or foreign nation detects their ops, then reports on it. Kaspersky already did with Equation Group plus used Snowden leaks to show it was probably NSA.
Anyway, we don't need them to publish anything. Just answer quick question: do you believe that the Snowden leaks improved people's ability to resist NSA surveillance and increase privacy through technological responses? Does that include foreign businesses or governments? If so, then you are already admitting that it reduced NSA surveillance and impacted their operations. One follows the other logically. Either Snowden leaks had no effect on NSA spying, making him a fail outside of legal reform, or they did negatively impact NSA by disrupting their operations.
"even if some small percentage of what Snowden leaked did harm US operations somehow... I'd argue that it was justified in light of the big picture,"
He wasn't justified because he didn't have to leak it. That simple. He could've just leaked the ones that targeted Americans or showed gross abuse rather than a lot of what we already, as Americans, allowed NSA to do. Instead, he turned over everything to many foreign media.
Btw, do you remember why he did that? Did you ever read the reason? He gave two actually. One sheds a lot of light on whether he had to do this and just how heroic he really is.
