Comment The recipient is giving the message to Google (Score 1) 57
What about people who didn't sign up for a Gmail account? Their mail gets scanned when someone with a Gmail account receives it. I wonder if Google creates "shadow profiles" like Facebook does?
Suppose you send me a snail-mail letter and my secretary reads it to decide if it deserves my attention. Has your privacy been violated? Suppose I take your letter and put in on the company bulletin board so everyone can read it. It may offend you, it may be socially gauche, but would it be illegal?
My e-mail secretary is called GMail, and I chose to let it read all my incoming mail. That's between me and Google, and I don't see why you (the sender of my incoming messages) has any right to complain. Moreover, the text of the incoming messages is only used to show me targeted ads, so I really don't see why you should care.
If (and that's a big if) Google put information from scanned incoming messages into its online profile of you (for ads on non-google websites), then there might be some cause for concern, but that's not what they do, and even if the did I don't see the problem. If you send me a message and I decided to let Google read it then Google should be in the clear..
