Your argument would be far more charitable if NIST had not already been caught pushing a broken standard at the behest of the NSA before. DJB might be combative and somewhat caustic, but the one thing he's never been, given enough time in the retrospect to show it, is wrong.

The logic you're using here would be just as valid in a campaign against SHA2. More valid, in fact, because unlike MLKEM, which was designed by European academic cryptographers, the NSA actually designed SHA2.
