Ok but ... isn't Microsoft forced, by law, to cooperate with the US government and US military? So why is that then not an ethical (or other) issue?
To me this seems inconsistent. The only "necessity" I see is for Microsoft to be penalised by EU laws, which could explain that "investigation" to some extent. But the EU in general is super-weak. They even give data from EU citizens to the US government as-is, without any problem, so I don't quite buy into that explanation. Is there another explanation that makes more sense?
