Facebook’s terms state Facebook can “record audio with the microphone … at any time without your confirmation.” The terms also allow for taking pictures and videos without confirmation as well. Here's a super simple experiment that proves this and shows how people (you and me, everyone) are being spied on by the social network.
Most people are not aware of this, but they should. Some people say: "I am not important or I'm not doing anything illegal so why should I care?". This is a very stupid argument. Would you like to be at your house talking with your spouse, couple, friend, parents or whatever and have a microphone broadcasting everything you say to who know where? NO. Obviously is not a matter of being important or not, It's just common sense that people need privacy in their lifes, like it has always been.... Until now, with all this abuse from tech companies like Facebook.
This info should be shared so people learn and uninstall that terrible app. This app actually has like a 1 score on the apps stores because people do not like it at all.
What do you think, are you uninstalling the app or not?
You don't have to have this app installed in order to check your FB msgs, you can use your phone's browser and visit facebook from the browser of the phone and read the msgs like that, bypassing the terrible messenger app.
