I find it really strange, amazing even that this is still a flammable topic. I mean, erosion of privacy is at the heart of Google's business. How does everyone forget this? They are a business and don't care about people or their privacy - its literally their opposition.

So, of course it makes sense that they would like the people whose privacy they are eroding to be in the dark about how much they know about them! Cos then they won't even know to protest! People are already forgetful, if the information is hidden too, in the dark Google et al will have free reign to do what they like.
