I expect to get a gmail type service paying only the "price" of having some unobtrusive ads when I'm on the gmail site, nothing else. I absolutely do not agree to google using anything from gmail to generate a stable user id for advertising, or e.g. show me ads in google search results or youtube videos, based on analysis of email content. If Google can't provide what I expect (a free mail service paid only by ads on gmail dot com) they should tell me that they want $X per year and I'd happily pay it. It's not that I don't want to fund the operations of services, it's that I'm always assumed to rather pay with my information than with dollars.
