Facebook deliberately hid and obfuscated its user interface to prevent people from selecting appropriate privacy options, and now blames the consumers for not finding the hidden options.

Sandberg is saying exactly the same thing as Zuckerberg, only with wording that is marginally more polite.
Their statements say much about what Facebook thinks of you.
