Remember, all AI companies openly claimed to oppose military usage just a few short years ago. Now they all have government contracts that allow the government to use them "lawfully", while also being able to decide that anything they do with them is lawful. Anthropic is the only one who required clauses against killbots and domestic mass surveillance.
Anthropic never asked for arbitrary or opaque shutdowns. They asked for clearly defined regulations to apply equally (which would've helped their market position and advantage, coincidentally I'm sure /s), moreso to reduce their own risk and liability.
