WhatsApp Lost Millions of Users, Company to Change Privacy Terms Weeks after rolling out the latest, controversial changes to its privacy terms, Facebook-owned messaging app company WhatsApp had lost millions of users. As noted from The New York Times, analytics firm App Annie reveals that the app has free-fallen from the top ten most downloaded apps to the 23rd by the middle of this month. "Due to the nature of social apps and how the primary functionality involves communicating with others, their growth can often move quite quickly, based on current events," Amir Ghodrati, the director of market insights for App Annie, told The New York Times.
