Mark Zuckerberg’s op-ed in the Wall Street Journal today (paywalled, but summarized here) relies on all-too-familiar refrains to explain the dubious principles and so-called “facts” behind Facebook’s business model... [A]s usual, it wildly misses users’ actual privacy concerns and preferences... To receive relevant ads, you do not need to submit to data brokers harvesting the entire history of everything you’ve done on and off the web and using it to build a sophisticated dossier about who you are... Pew found that 74% of U.S. adult Facebook users didn’t even know that Facebook maintained information on their advertising interests and preferences in the first place... Zuckerberg deploys Facebook’s favorite PR red herring: he says that Facebook does not sell your data. It may be the case that Facebook does not transfer user data to third parties in exchange for money. But there are many other ways to invade users’ privacy. For example, the company indisputably does sell access to users’ personal information in the form of targeted advertising spots.
