There are lots of companies who have need for cryptography who don't know who to trust. What should they do in a world where the standards bodies are adversarial?
Maybe this is just the future, if you don't know crypto you're doomed to either do the research or accept that you're probably backdoored? Seems like a rough place to be...
For example, we built private information recovery using the first production grade open source implementation of oblivious RAM (https://mobilecoin.com/overview/explain-like-i'm-five/fog you’ll want to skip to the software engineer section) so that organizations could obliviously store and recover customer transactions without being able to observe them. The signal protocol’s techniques might be part of a cryptographic solution but it is not a silver-bullet.
I guess, notably, we never looked at NIST when designing it so maybe that’s the end of the discussion there.
