Re: You are number 6
This, exactly.
The fact is, data about me is worth far more to Google than it is to me. I couldn't begin to monetise it the way they do. I wouldn't know where to start. So why should I begrudge it to them, when they give me a whole raft of useful services in return?
Yes, they know what I'm likely to buy. I still don't see almost any ads (thank you, Adblock), and those I do see are more likely to be of interest to me. Is that a bad thing?
Yes, they know where I live and where I work. I have no objection to them knowing that, provided I'm reasonably confident it's not available on demand to any old nutjob who asks - and I am reasonably confident of that. Yes, they probably know what I do for a living. They may know who I bank with, who I do business with, what sites I browse, what kinds of porn I enjoy. But I have faith that they're not going to use any of that information improperly, because there's no plausible way of making a profit out of it.
And sure, governments may be able to access it too. People have this fantasy about the secret police kicking in their door one night and dragging them off for re-education, or something. In the immortal words of Slaartibartfast: "That's perfectly normal paranoia, everyone has that." Face it: you're not that interesting. Not even your porn collection.
