The two most important things to understand about this kerfuffle:
(1) MLKEM wasn't designed by NSA, but rather by a team of highly-regarded European academic cryptographers, including Bernstein's former collaborator Peter Schwabe; their submission, Kyber, was selected in an open competition in which Bernstein himself submitted a closely-related algorithm (and then contested the result, suing NIST for documents to clarify the selection.)
(2) The RFC at issue documents the possibility of running TLS with pure MLKEM rather than in a hybrid configuration with ECDH. Hybrid TLS is already the mainstream, documented, standardized method for using PQC in a TLS connection. Bernstein is canvassing opposition to any documentation of the possibility of pure MLKEM in TLS.
Every time Bernstein talks about NSA's sordid history, remember: nothing that's happening here has really anything to do with NSA. It would make more sense for Bernstein to be canvassing against SHA2, which NSA actually did design. But he can't do that, because normal people know enough about cryptography to understand how crazy a claim that is. Unfortunately, we can't yet say that about lattice cryptography, despite it being approximately as well-studied as ECC.
