I'm familiar with DDG, donttrack.us, dontbubble.us. My question was because even without an account or using its search engine, with AdWords and other products, Google is able to track people to provide them – and those who fall in the same bucket – targeted advertisement (which is what Facebook uses the same data for). I am not much concerned about this – but I'm starting to, sometimes it is actually a bit creepy –, but I see a lot more people concerned about Facebook tracking them than Google, which I don't understand, since Google has been doing it far longer and in a much more pervasive way, yet very few people express concern about Google these days. I remember the uproar when Gmail introduced content targeted ads, but now nobody cares anymore, directing all attention only to Facebook. Tangentially, the issues raised by dontbubble.us concern me more than being tracked.
