In reality, most apps/social media probably spy on us.
We were at my MIL's tonight and she brought up something neither my wife or I had ever heard of. So she tells us about this stupid thing, the end.
Then my wife gets home and checks Facebook on her phone and voila, all of the sudden she is seeing adds for this stupid thing. Neither of us had searched for it, heard of it, etc....
So I check the privileges Facebook has on her phone and sure enough, Microphone was turned on.
Them dirty little fukkers
