You're never going to find any large organization that satisfies all of your wishes, even a non-profit has internal political struggles.
But on a relative scale of evilness, which big companies would you want to work for? For example, Apple (Doesn't trust employees, has them work on fake products, super-compartmentalized secrecy on campus, has agents spying on people to stop leaks, abusive douche-bag boss (Jobs) of shitting on people when the demo doesn't meet expectations, squeezing all partners for every last nickle, super-controlled closed proprietary ecosystem, on and on)? Apple sounds like a place to work on amazing products, but shitty otherwise.
Google made a mistake by coining "Don't be evil", because they are held to a much much higher standard now than any other company because of it. The smallest change or transgression is hyper-analyzed by a cadre of people just waiting, sometimes wishing, to find a mis-step, anything they can run to the blogosphere with and claim "See! Evil!"
Basic cynicism in people seems to relish those who preach superior ethics to fail. A guy who talks about "Don't cheat on your wife" will be scrutinized much more than someone who doesn't. And if he is seen in public having a business dinner with an attractive lady, of course the stories will be "See! Mr White Knight is unfaithful!"
The place reeks of lack of trust and just sounds _depressing_ to work at.
