$20 a month for all your data for Facebook, what a joke, Facebook users must be insane. Facebook is now paying users for their new app $20 a month for access to all data. They must have gone bunker. how far we they go for users data?.So, if the app connect through a WiFi ,then Facebook will collect the user's data and the network and any devices connected to the network. Unfortunately some zombies have started using it. Don't allow any one with the app on their phone to use your WiFi .
