This is kind of ridiculous. The "don't be evil" slogan originated in 2001 supposedly, when Google had $7 million in profit and very few employees. They were hardly a powerhouse, although things looked very promising at that point.
The founders of Google were visionaries who understood the humanity involved in any large organization. The very slogan was introduced to help them remember not to do bad things when they get big. Unfortunately, it hasn't worked out that well.
