Well, first off, Google has a privacy policy [1] where they commit to not publishing my entire works without my consent.
Even without that, though -- what do you think would happen if they did what you're suggesting? I think the public punishment would be worse than any legal repercussions.
And that's what it comes down to, IMO. I regret that we have to have these far reaching policies and agreements filled with legalese, but there is also the social contract.
Of course, what you say about data mining for ads is true. If you don't want to expose yourself to that, don't expose your data to Google.
