Green explicitly mentions Kyber in his post.

And it's not just Signal. Apples new iMessage protocol, PQ3, uses Kyber, too. [1] Most deployments of PQ-crypto that I know of have used Kyber.

Kyber is the fastest KEM after Rainbow. Once Rainbow was broken, Kyber was the obvious choice. NIST delayed as long as it did to perform due diligence.

Rainbow is not a KEM, but a signature scheme.
