Personally I think it's a bit of an overreaction to the kind of data they collect. D: They aren't putting that data to faces or real people. It's all automatic tagging and ad placement based on keywords. They only get as much as you give it. So unless you're a psycho who has been using google to hunt down kids for sex, a crazy bomber, and using the internet like a total idiot, then it's prooobably not going to ever effect you. XD
Things like SOPA/PIPA have a much bigger and widespread impact. @___@
