You did say that privacy concerns are essentially concerns about how [FB] will look at and use the data. Which is actually my point as well - privacy is much broader than which of my friend and followers will see what I post. It is even broader than which third party apps have what access to my account -- yet the article makes it seem like those things are the only privacy concern instead of just a subset of it. Agreed they won't share your information with third parties or use it themselves without permission - but they myriad of ways in which they ask for that permission, and in which you default to giving it means it serves only as the loosest constraint. By default users allow them to perform analytics that reveal a disturbing amount of information about them, among many other things. Similarly, I think the notion of privacy in which data you share is quite silly - if you're sharing stuff on the Internet, you should expect it to be public for all time. No matter who you're sharing it with or through. However, I would also expect the company I'm sharing through to act only as a middle-man, and not use my data for its own ends*. (That seems to be a different take on the silly angle that you have. )
