Making bomb components and missile guidance systems is not evil in itself. If only evil men made and used weapons, the world would be in very bad shape.
I'm not arguing that the specific weapons mentioned weren't used for evil, I'm just making a general point that all the peaceful people in the world can afford to be that way because there are guns protecting them, so it's not as simple as weapons == evil.
Unless of course the first thing GOOG does is wipe out all the IP and Patents owned by Motorola that have anything to do with... you know, killing people.
