The problem is that it's up to the folks at Facebook to decide what connotes "non-personally identifiable attributes." We've written at length about the problems with Facebook's protean privacy policies, and the company has done an admirable job of addressing user privacy concerns by offering users the option to disable troublesome features like "Instant Personalization," which allows third-party websites like Huffington Post and Pandora to access your Facebook data in order to customize their services with ads you might click on.
Of course you never retain complete control over the data you post; Facebook reserves the right to use your name and image to promote any product or service you endorse, which means that your Facebook friends are likely already seeing ads for the latest summer blockbuster with your face attached. Worse, if you use the GPS function on your phone to check in at the local REI outlet and REI has paid for a Facebook Sponsored Story ad campaign, your name and the details of your check-in may appear without your knowledge as an ad promoting the REI brand to your friends and family.
"Facebook has a history of privacy problems," writes Ben Edelman, an assistant professor at the Harvard Business School who specializes in online business. "New features introduced without a full assessment of privacy consequences; settings changes that reduce users' privacy unexpectedly; transmission and sharing of data contrary to Facebook's promises to users. In this context, users rightly look for alternatives."
