The word "legal" is doing all of the heavy lifting. Considering the countless adjudicated illegal things that the government is doing publicly. What happens behind classified closed doors?
I guess you can consider it a moral stance that if the government constantly does illegal things you wouldn't trust them to follow the law.
I know that's not what Anthropic said but that's the gist I'm getting.
Does legal include international law, which the US has broken numerous times the last two days?
