If Google really wants to "not do evil", they should actively work on removing themselves from this position of power they have. They should also work on making it impossible for any entity to obtain this kind of power. That is certainly a very difficult task, but there are little things that can be done and would make a difference (real support for freenet, bitcoins, or wikileaks).

Just gathering power is evil, because in a few years the temptation to use the power will be too strong.

Also being a public company complicates the strict "Don't be evil" logic. Shareholders, in general, doesn't care about being too ethical in a metaphysics sense.

It's time to think that private companies has a most promising ethical future than public ones.

I think you can only say that, if you measure this on a spectrum, they only have a wider potential range of evil:good. Any conclusion about clustering would be founded on an utter lack of data.
