Google is not evil by nature (though i have my own doubts) and Facebook is also not evil by nature. Facebook simply has a different philosophy on _sharing_. They believe that people should share everything and be more social. If this is not something people are not comfortable with, then those people have no business in signing up for facebook and complaining that everything is shared by default. As far as Google's privacy 'glitches' are concerned, in my experience bugs make it into production accidentally. But pieces of code that are developed specifically to sample wifi packets that might contain sensitive data or code that exposes all my email contacts to the entire world do not make into production accidentally.
