Google never tried to change its core product the way Facebook has. Facebook started as a private network of close friends and they've changed it to an open network of friends, family, and the world. As much as they've changed about the product, they cannot change users' perceptions, which have remained the same throughout. They've basically caused their users to suffer from cognitive dissonance about what Facebook is vs. what they expect it to be.
