Anthropic wanted the ability to verify compliance whereas OAI and Google are fine with "trust us". Which is how it always is, and always has been.

For better or worse, the government is the one who audits, and has it's own internal systems for self audits. So no one except them tells them what they can or cannot do. The government would never put itself in a position where civilians died because Amodei didn't like the vibe of the case being worked.

In a way it's wild that people are upset that the government didn't put a billionaire megacorp CEO in the drivers seat of intelligence.
