The problem with "Don't be evil" is that it's subjective. Google isn't a hardcore idealist because people that refuse to cooperate unless all of their demands are met never really get anywhere (see RMS). Compromise is a fact of life for everyone. Principles shouldn't be compromised, and you have to draw the line, but you also have to cooperate with people who have a different perspective than yourself.
I don't see either censorship in China or the net neutrality proposal (which I don't know much about) as bonafide "evil". You may disagree, but it's hard to say that they are evil or done with evil intent.
Oracle, on the other hand, is pretty easy to call evil because they act out of cruel self-interest practically exclusively. Oracle is always taking cheap shots.
