Earlier quoted context omitted.
We're not talking about the relationship between her and Google, but the one between her and her ex-husband, into which google has unwittingly interposed itself.
She willingly included Google in that relationship by making him a contact and giving Google information that they had a relationship. You can't give away information and expect it not to be acted upon. Corporations are not bound by anything except for the law and the contract they form with you. If it's within their rights, they can and will act upon it.
The second is that all the people that frequently contact HER (via an anonymous account which forwards to her Google account) now have her personal Gmail account and are following her on Buzz (and Google Reader), which she can't stop from happening.
The problem is that Google's assumed that anyone with whom you correspond frequently is a friend with whom you're willing to share all of your data, when in reality a lot of people are forced to correspond with people whom they don't like at all, and that Google shouldn't be saying 'Hey, we've created a new thing called Buzz, and we've told everyone all about you on your behalf!'
Edit: also worth mentioning: you don't 'make someone a contact' in Gmail, Google does it for you automatically whenever you e-mail someone. Also, she didn't give Google information that they were in a relationship, Google just did this automatically. Even people that she e-mailed from an anonymous address via gmail got access to her profile. Google basically gave everyone her personal info without asking if it was ok, and now she can't take it back.
