People often feel like Facebook keeps the mic open on their phone and listens in on their conversations. How else can you explain the targeted ads? They assume that their smartphone is always listening to what they have to say, pulling information from the conversations they have, and sending them ads based on what they talk about. Talking to your spouse about buying a car? You'll get ads for a car. Telling your friends that you're looking for a new comedy to watch? You'll get ads for streaming services and all of the new shows that are coming out. But is Facebook really listening, or is it something else?
