Facebook’s Privacy Pivot

Controlling what my friends see is the least of my concerns on Facebook.
They even pass secret laws about it.
What might be less apparent is that this is a great way to make a news feed more relevant to people. By having posters self-select who sees what, it reduces noise and make's Facebook job easier for determining what content is displayed in the feed.
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. )
In the beginning, Facebook was, to some extent, private. I'm thinking back to the days when they were rolled out college by college. Even after then, mostly people of a certain generation were on FB.
Since then, their reach has gone global and it reached the late adopters: parent, grandparents, uncles and aunts. As that circle became larger, Facebook felt less private.
What the article seems to have missed is that the popularity around other sharing models is actually relatively new. 1-1 messaging, at least on mobile, really only got huge within the last 2-4 years. How old is Snapchat? < 3 years? And it's been mainstream-ish for less than that. Secret, Whisper, Kik... all of these apps with different sharing models are a pretty recent phenomenon.
It seems pretty silly to call this an "about face" considering the span of time considered. Opinions always evolve over time. Look at Steve Jobs: Famously known for saying that Apple would "never" make a tablet smaller than the original iPad. Lo and behold, they did.
Products and the philosophy around them change over time, especially in an area like tech which is quick moving and ever-changing.
