If you are interested in helping out and stopping the spread of something like coronavirus, these apps can be very useful," Neff said. "You just have to know the cost of the privacy you are giving up. But, a lot of us do this every day with Facebook, Instagram, and Twitter."

Taking away your privacy and freedom little by little and before you know it you have none.If that isn't concerning I dont know what is.By putting information up on social platforms you are giving information that you dont even realize ..for example just liking something is enough for data miners to create a profile on you..this is how Trump won the election..they spent the money targeting people they felt they would get votes from by using Facebook data instead of wasting money and energy on votes they would never get.
