It's a religious impulse. It may not be literal religion, in the sense of believing "God says this is the right thing to do," but it is the same underlying instinct - "This is Right, and I must do all in my power to serve it."

Once they are, groupthink and lack of dissenting opinions means the company starts to explicitly support whatever causes fit its corporate culture. That's what it looks like to me, anyway.
