That's the kind of retaliation I can get behind whole-heartedly :-)
NSA guy #2: "Sure, let's release our Google zero day!"
#1: "Oh, but didn't we spend millions on that?"
#2: "Yeah, but it'll really screw up Google!"
#1: "Okay, do it."
Google: "Oh my, thanks for pointing out that exploit. We're so glad the NSA is getting back to its mandate to alert American companies and organizations when it had identified security holes. And....fixed. Let us know if you find any more!"
I'm with GP on that we need more programs like project zero.
Please get angry and do it Microsoft! Show Google how it's done.
