Well, I know it's an unpopular view, but I think the US government doing that was okay. I don't pretend that's grounded in principle; I don't think that other governments should be able to do it, or that there was no potential for abuse. I think the national security rationale for the programme was valid. (perhaps not in law, I acknowledge)

I agree completely that the leak was very significant, but my preference (I think; not 100%) would be that Snowden hadn't leaked.
