Indeed. Dual_EC was a NOBUS backdoor relying on the ECDLP. That's fair.

My point was more that it looked suspicious at the time (why use a trapdoor in a CSPRNG) and at least the possibility of "escrow" was known, as evidenced by the fact that Vanstone (one of the inventors of elliptic curve cryptography) patented said backdoor around 2006.

This suspiciousness simply doesn't apply to ML-KEM, if one ignores one very specific cryptographer.
