Why? That's kind of the whole point of this: they can cooperate entirely and give them everything they have. You think they'll get into legal trouble because they aren't gathering data?
There are a number of companies/products that operate under this principle (mullvad and signal come to mind). Are you saying all of those are futile and misleading? Or are you saying that you expect they all have significant money and legal teams to defend against a crooked cop's thirst for vengeance for not responding the way they wanted during an investigation?
