Institutions of that nature are incapable of following through on nearly any promise made to the public at large; every promise is a lie, whether they break it or not, because they can't be said to have the intention to uphold it.
I see no reason not to believe that Page and Brin sincerely desired Google not to be evil; but it's the institution decides to do evil, not any individual, so they did not have (or could not maintain, as the organization scaled) the power to guarantee this. No one does.
Just location tracking. The lies. Over, and over, and over, and over again the lies.
