Eric Schmidt, as Google CEO, had a habit of saying unpopular but true things. When he responded to a question about how people interact with Google with "If you have something that you don't want anyone to know, maybe you shouldn't be doing it in the first place," he wasn't so much offering self-criticism as a warning regarding the overall societal trend, of which Google was merely a part.

Privacy is generally agreed to be a human right. And privacy means that you can do or say something and have a right to have it not be known or made public. If someone with access to you data exposes it, it's a violation of privacy. So no, the old argument of "if you don't want it known, don't do it" is fallacious and dangerous.
Correct, but not a universal, constant, perpetual one like life and liberty. It is situational and context-specific; for example, it is not assumed you have a right to privacy regarding what you shout in the public square.
The still open question is the scope (perpetuity and breadth) of that right regarding things like the information you query on a publicly-accessible third-party search service... Does it look more like the privacy around what you do in your own bedroom or around what you do in the public square. And we have precedent that pokes at this topic... One's banking affairs, for example, are relatively private, but the state has a vested interest (taxation and investigation of a crime) in acquiring that information in special circumstances, and banks can and will divulge their copy of that information upon due legal request from the state.
I think it's hard to build a case that you have the same right to privacy as a bedroom right regarding information that you have queried in a third-party's database over a public network. It certainly seems like the jury is still out on the topic (and has been for two or three decades now, at least).
