I Don't Use Gmail, but Google Still Has Lots of My Personal Emails
A few years ago, I was surprised to find out that my friend Peter Eckersley—a very privacy-conscious person who is technology projects director at the Electronic Frontier Foundation—used Gmail. I asked him why he would willingly give Google copies of all his email. Peter pointed out that if all of your friends use Gmail, Google has your email anyway. Any time I email somebody who uses Gmail—and anytime they email me—Google has that email.
