Google is in the news again for privacy violations. Seems their cars that went around photographing your neighborhood so they could show them on Google Maps were also recording your personal Wi-Fi traffic.
Now that they have been found out they are very apologetic, but the point is that they did it.
It just goes to show that you can't relax when it come to privacy on the Internet. And you can't regard any company as totally trustworthy.
