“If we don’t create the thing that kills Facebook, someone else will.”

Those are Mark Zuckerberg’s words, in a little red-orange book handed to new Facebook employees, according to reporter Sarah Frier’s award-winning book No Filter: The Inside Story of Instagram. In an excerpt from the book on OneZero, Frier explains how Zuckerberg’s paranoia that Instagram might become the more popular social network drove his decision to acquire it. Yesterday, the FTC and dozens of states filed two antitrust lawsuits against Facebook, with the aim of requiring it to divest WhatsApp and Instagram. The thing that kills Facebook might be created by someone else after all.
