Glad I didn't install the app and honestly more reason than ever for me to delete my FB account as I've been wanting to do lately...

...recently I discovered that Facebook has sold me out. In numerous ways, in fact. Did you know that with the new Messenger app that Facebook has forced upon us, you have given Facebook the right to tap directly into your camera and microphone while using the app? That's right, if you are reading this article from a Facebook link, a Facebook employee or two may be critiquing your new haircut right now. You may have guessed that Facebook uses your activity to predict your interests, and sells this information to advertisers. But did you also know that it's been reported that the user agreement not only gives Facebook access to your activity while on Facebook, it gives the company the right to monitor ALL of your online activity ALL of the time and on ANY devise where it is installed?!
