Google is not evil. They are trying to improve that's why there are changes. but still we still have our own opinions regarding this as our sites gets affected by random changes they made.
Personalized search seems a bit evil to me in a way that it is tracking your search habits which is kind of creepy. Also the buying up of anyone that either has a better idea than Google or can compete with them is a bit evil but it is an American based company and it is a free market enterprise is a free market economy. More power to them if they can build a better mousetrap.
They are a private business so it is obvious their actions are directly related to more and more income for them.
I liked Google at first, they seems to turn to contrary way like microsoft. Google will die soon anyway, japan build SE with a intelligence wisdom. Google will be sorry for what they did.
