Recently my girlfriend discovered the depth of the program FB started to listen to the microphone, even if the app isn't on. She never installed the FB app on her new phone. Multiple times in the last month, some VERY specific topic of conversation IRL has shown up as an ad in her FB stream. Most recently, a coworker told her about a "Custom Martin" guitar he had just bought. Later that day there was an ad for a custom Martin guitar. She's never searched for that, liked anything related, there's absolutely no other reasonable explanation, and facebook has made it clear they were going to start listening. They were serious. We later discovered that new Samsung phones have FB installed as a "system app" that can't be uninstalled, and that app has permission to turn on the microphone whenever, without permission. Her phone listens to everything she says all day. Anyone with the FB app (whether they choose to install it or not in the case of Samsungs) is being listened to at all times. To me, this is worse than every single thing on RMS's list. It's kinda terrifying.
