If I could be given a bit of latitude to generalize for a second, I've noticed that America has a very "self-focused" culture wherein the individual is often seen as being solely responsible for everything relating to their self.

That makes a lot of sense but I've seen this often taken to extremes such that the perspective is used to absolve various levels of government, corporations, and organizations from responsibility over making decisions about common goods or on the behalf of others (things like healthcare, safety/protection, insurance, privacy, etc.).

So this position from Facebook seems (to me) to be a very American approach to take. ie. "We give you a plethora of options to secure your information, thus it's on you what information we get. After that, once we have it, then its ours and not yours anymore."
