Um.. How about the escape of not putting all your private information up on the internet in the first place?
I'm on Facebook, but don't have ANYTHING I don't want kept private on it. It has my real name and photo, plus a few other photos I've uploaded at various times, but doesn't have my email exposed, or phone number, job info, birthday, relationship status filled in at all (well birthday is, since they require it, but the birthday is the wrong month, year and day so fat lot of good that does them for marketing) It is a good way to keep in touch with people I otherwise wouldn't, and a good time killer. It is quite possible to be on Facebook without "putting all your private information up on the internet".
My concern isn't giving them private info, that's one's choice. I chose one way, others (either less clueful or more trusting than I) have chosen differently. My concern is the kind of crap they tried to pull with Instragram, and even themselves in the past - but luckily had to backtrack both times after a big outcry. I don't want them using my name or photo in ads they show to others. That's just plain wrong, and luckily even the "over sharers" on Facebook seem to realize this, based on the size of the outcry when Facebook tried it the first time and when they tried it again with Instagram.
Whether these ads would say "Doug uses an iPhone, you should too" (which is true, they know because I access FB using the iPhone app) or whether it was something totally random like if I happened to 'like' someone's post about a Dodge Charger, then they use me in a Dodge Charger ad, I don't want it. If Facebook wants to do that, and gives me the choice of ALLOWING them do it and getting paid for it, like everyone else who shills for a product, fine. But they damn well can't just go ahead and do it without my permission, and the minute they do is the last time I ever login to Facebook. And it looks like I'd be far from alone. That type of mass exodus off Facebook (regardless of where people went) has so far been a powerful enough threat in terms of lost revenue that they don't consider it worthwhile tradeoff for "improving" their targeted advertising to those who remain.
