My problem in this whole data privacy debate is things like "shadow profiles" where even though I don't have Facebook, they still have information on me because one of my friends decided to share their entire contacts list with facebook and thus facebook now knows my details too even though I never consented to my details being shared.
Another problem I have with this privacy debate is the lack of technological awareness in the politicians. I watched the US senate hearing last year with Mark Zuckerberg and was absolutely shocked at how clueless the members in office were. It was shameful. Mark also got away with giving almost useless answers and the senators didn't grill him much on more important issues.
At this point, I am really curious whether our data is even valuable in the "ad market" considering everything gets leaked anyway. So if something is getting so easily available to these ad companies by simply "misusing" the service, wouldn't the value of the data start going down? I remember a few months ago, there was an article on how the data per use was valued at around $12 (not sure if I am remembering right). I wonder if that value goes down over time because of these so claimed "breaches".
