I find Googles' invasion of privacy a big turn off. I have long since stopped using Facebook for exactly this reason. I am not quite at the point with Google where I say I don't trust them, unlike Facebook. I regularly check out DuckDuckGo but its search results are not quite there yet for me, in comparison to Google. At this stage the gap is narrowing, both as a result of my increasing concerns over the invasion of privacy from Google and the increasing quality of DuckDuckGo.
It is only a matter of time before I say goodbye to Google forever....
