Why not go ask Matthew Green if EKR is "corrupted"?
I feel like yours is the kind of critique you can only write after not having read my piece, as it suggests I think that Margaret Salter, an employee of the NSA, is "uncorrupted".
If you feel like suggestions that EKR might be an NSA plant are greeted with derision, the level of research and insight people bring with that very serious accusation would be why. EKR helped write Dual_EC!, they suggest. EKR's defenders think Margaret Salter is just fine! they assert.
Can you find any professional cryptographer or crypto engineer that has publicly suggested EKR is working for NSA?
