Facebook sold our stuff to governments & advertisers. They monitor our phone calls, believe it or not. That is what many have said. Some people say they don't believe that happens. Some say they don't care. You know they listen in for key words like the word "BOMB" for example. They say they have to monitor us for our own safety. You can see this thing happen in the USA, especially, and in other countries too.
Watch the Bourne Identity movies.
Watch the Matrix films.
How long have they been doing this? Decades or maybe even centuries. Watch the television show called the X Files for example. If they can get our private stuff, then they can frame us better, manipulate us better, and use our info against us. They can black mail us better. They can find us faster if they want to kill us or take our money or lock us out of our money / computer / internet / Bitcoin / Steemit / and more.
Watch Wall-E.
Watch Z for Vendetta.
Watch the show Nowhere Man.
