Please note that mass surveillance of Europeans is fine from Anthropic's statement.

It's called political correctness. There is a longstanding undercurrent in American politics of treating Constitutional rights (aka natural rights) as only applicable to Americans [0]. Framing the issue in terms of lofty universal ideals would be politically suicidal. And with the current precarious situation, giving more energy to overly-simplistic jingoist chants is not what anybody needs.

[0] this seems to be a bit of proto-fascism that helped set the stage for the overt dynamic we've now got

Yeah it's a shitty statement "we're totally fine accidently targeting foreigners but come on, not 'mericans" because it's well known that once you have the capability it will be aimed at everyone anyway.

Folks; there isn't a geopolity agnostic equivalent of incorporation. There is no Anthropic without that grant of incorporation. Even if they wanted to take the most principled stance, they can only push so far, and to have a system that is incompatible with operating a mass surveillance network, it has to be capable of monitoring itself to recognize whether it has been configured in such a way as it's activity is aligned to the activity of mass surveillance. You'd have to build the mass surveillance oracle, which is in and of itself, a mass surveillance machine.

Europe is not particularly anti surveillance

Actually the EU passed an AI act back in 2024 that tackles that.
