I'm no FB apologist, but I take issue with this:

> fake account problem … Google Trends shows worldwide "Facebook" queries down 80% from their November 2012 peak.

Except that much of this downturn in people googling "Facebook" is explainable by the shift to mobile. Surely no one needs to Google "Facebook" to open the Facebook app on their phone’s home screen. (For that matter, one doesn't even need the app icon when one is receiving push notifications from FB. No legit notifs? No problem, FB will synthesize fake ones.)
