Google, from its conception, is already supported by the US government to act as United States eyes and ears.
That's why Google won every monopoly charges in every court.
Guess what happens to previous search engines, such as AltaVista, which may refuses to cooperate with the "black suits".
Since years back, we know that US government didn't give a fuck about our privacy.
So does Google.
So does Facebook.
So does Apple.
So does Yahoo.
So does Microsoft.
And then we know that all of these companies are involved in some NSA shit to invade our privacy and to spy on us.
Yes, we may bank from Google, but we should not trust them, and see them as a good guy.
Google has left its "do no evil" policy years ago. I bet "do no evil" is just a hollow slogan anyway, which they never plan to respect from the start.
