There’s two layers to it. With a sufficiently large enough org, you can build it in discrete enough parts (assuming it’s a building something based) that only the one who creates the final part is the one who knows what the ultimate goal is or the one who pulls the trigger. These people are also high enough to be inured to any effects of their decision. The second layer is even if you can see where it’s going and you do care, is it worth it to speak up and get fired? I know whistleblowers are meant to be protected (speaking only for the US) but with at-will employment and certain conditions that favor employers, how do you know they won’t cycle in someone who will do it anyway?
