Because you don't know that you can just cut the data wires in a cheap USB cable, and want to be 'protected' by a cool hipster toy that'll sit in your laptop/phone baggie until you're at some party and can shout in triump when someone plugs in their phone 'just to charge': "NO, USE MY USB CONDOM!!"

EDIT: if this thing actually had some diagnostic LED's that would show you that the 'power port' was trying to do something nefarious on the data lines, it'd be a lot more useful than an ultra-cheap snipped cable imho ..
