Charge-only cables are also in demand as a security measure for people
wishing to safely charge devices on random¹ USB ports found out in the
world.

In an ideal world you plug your device into a USB port and if whatever
it is connected to wants to do anything other than negotiate charging
then positive action has to be taken by you. But, software has bugs and
some people want a second level of defence.

In the other direction, infiltration has been done by leaving USB sticks
on the floor of the car park and hoping some employee plugs one in to
see what's on it. Some workplaces physically disable USB ports on their
computers because of things like that.

Thanks,
Andy

¹ Still not the best idea because there is no promise that such a thing
  wouldn't maliciously supply high voltage from mains or a capacitor.
  But there are people using charge-only cables to avoid malware.
