Please stop freaking out about Facebook Messenger, it's nothing new. OMG. You would think the sky had fallen. Requiring mobile users to use a stand alone Facebook Messenger app has created a stir among users that rivals the leak of the Snowden documents. Please, people. You are already giving a lot more personal information to other third party companies without a peep. Facebook has a lot to lose if it misuses your data. If it happens, it won't be intentional. Learn to love the mobile messenger. Don't kill the messenger. Embrace the future.
