This is a lot of words to say "you're right, Anthropic does not have any legal way to release frontier cyber capabilities to the public"

Right, so according to you it's because of the US government that they don't release it to the public? Have you missed their constant and incessant fear mongering?

The causality chain here was not "US government says its dangerous -> Anthropic can't release it", it was "Anthropic is fear mongering -> US government listens to their fear mongering".
