Invasion of privacy. I don't need Google sharing my email address with people in my address book. If it is not illegal it should be.
If you don't want to share your gmail address with all the people in your address book (maybe your boss or the human resource person) I would not click on the g+. I am sorry I ever kept a gmail account.
