Elimentals, you may know how to anonomise your device and that it is wise to do as far as possible, but by far the majority of people out there have no clue about these things. Yes, it is impossible to stay off the grid/net and not be tracked in some way, but we need to know what we are doing (giving away). This "opting out" way of doing things is already saying something. Why not "opt in" after a proper explanation? Opting out is often hidden and not obvious to the average user. Doing it this wrong way around is abusive and arrogant. Most people don't understand what is at stake.
I'm a technology/gadget freak like most here, but I do see the dangers of riding this tiger (getting off becoming less and less possible). I do have strong reservations about Google. Whoever controls Google and Facebook has much power. And we know that Google is working very closely with the NSA already (combine those two systems and a beast arises). This beast may be my friend today, but who's to guarantee me that it will be so tomorrow?
