Online fun brings new privacy tradeoffs

Facebook is following you around the web. You knew that, right? How else would Facebook know to serve that panda video straight into your newsfeed, and leave your college friend’s ill-informed rant about Pacific trade deals in the dark bowels of its servers? How else would it know to serve you with 7,000 ads for wedding dress vendors the very day you announce your engagement?

Facebook knows what you like. It knows what you don’t like.

This bothers many people, especially since Facebook keeps expanding the list of things it knows about you, and the ways it is willing to use that data to make money. The recent announcement that Facebook would soon target ads using your “likes” and “shares” has triggered some Olympic-level teeth- gnashing from the Electronic Frontier Foundation, because Facebook will get information from you not just when you actually like, “like” something, but when you load a page that has a “like” button on it. They want Facebook to use a “Do Not Track” standard that will keep all that data from the greedy eyes of advertisers.

Of course people should be able to hide data about what sites they use. But there’s a perfectly good way to do this: Stay signed out of Facebook and tell your browser not to accept cookies, or otherwise let advertisers follow you around the web. The problem is, this level of security is incredibly inconvenient, because you have to spend a lot of time painfully re-entering data. The other problem is that naive users, who probably don’t spend a lot of time thinking about privacy, won’t bother.

But what obligation do companies really have to naive users who don’t spend a lot of time thinking about privacy? Some of these users undoubtedly don’t realize that they are exposed, but we should not reject out of hand the possibility that most of them really don’t care enough – at least, not enough to put up with all that inconvenience.

For let us remember that, dingy and dispiriting as it may be, these companies do need to make money. There’s an old saying in advertising: If you can’t figure out what’s being sold, then you’re the product. “Free” products and services usually aren’t; someone has to finance them, and if they’re not charging you for your use, then they’re charging someone else to use you. Privacy-obsessed folks who carefully hide their activity from the Internet, and ad-hating readers who install blockers, are effectively having their free media and social media platforms subsidized by the folks who don’t know or don’t mind.

Privacy matters, but privacy is not free. And the best people to assess the tradeoffs between privacy, access, and convenience are probably the individuals wielding the mouse, rather than the activists wielding the megaphone.
