You think there is no profit to be made in wiping people's cell phones? Ever hear of blackmail? How about terrorism? Think there is no profit to be made in selling technology to mass kill cell phones to terrorist groups who might want to cause problems? There is profit to be made in exploits if you really think about it hard enough.
I was referring to the parent post who said "deactivates and wipes EVERY PHONE", which would not be very useful. There are much softer targets already for people looking to cause mayhem, and even terrorists use cellphones.
