It's the "no one is harmed" part I strongly disagree with. Perhaps they signed up for something and have perfect knowledge of how Facebook will use the information they collect (doubtful) but the rest of us will be impacted, manipulated and harmed in some way by what Facebook ultimately ends up doing with the data that their guinea pigs willingly gave up.
> It's the "no one is harmed" part I strongly disagree with. I can't prove a negative. So you would have to prove the positive, what harm came from this app?
Then why do you assert it as being truthful?
The history of FB's data collection practices is replete with "harm".
