Just wanted to acknowledge how brilliant that is. They could have made any other code change, but it was genius using NSA's own backdoor.
NSA advocated for that backdoor to be included in the standards. The US government then would be embarrassed and would want to cover up any issues related to it, including the fact that it was taken over by someone else!
Gotta wonder what that Monday morning meeting was like at the NSA when they realized what had happened.
