The only thing Greenwald has done wrong is be overconfident in his ability to report accurately on technological specifics he doesn't understand. And I don't see how the resultant errors have hurt much of anything. The main impact of his reporting is to get people out of denial about what they sort of knew anyway, namely that the NSA has access to lots and lots and lots and lots of otherwise-private information. EXACTLY which kinds of information the NSA has, and which kinds it's still a few years away from securing, hardly matter from a public policy standpoint. Little practical harm is coming to innocent people from the snooping right now; the risks to liberty over time are horrific, and so something must be done to rein them in; those things are true under any reasonable theory as to exactly what data the NSA does or doesn't already have.
