I didn't assume that, and laid out the argument why it might have happened above. I don't take a stance on the question of whether the NIST curves are OK either way, other than to defend those who argue there might be a problem (in the past I've seen this take dismissed as a conspiracy theory, which is clearly absurd). There isn't any specific evidence that there's a problem, only a failure to uphold the highest possible standards, which is a fairly weak form of evidence.
