Google, WiFi, and Signs in the Front Yard

I find myself shaking my head in astonishment at the fuss being made about Google's capture of some data transmitted on unsecured WiFi.

Having a WiFi router you have not secured, and then complaining that somebody read  what you transmitted, is like putting a sign up in your front yard and then complaining that somebody read it.

It's unprotected, for crying out loud! Anybody can read it!
