Cars support drunk driving. Therefore they should be banned. Jailbreaking, just like a car, is a vehicle designed to make life easier for people in various ways. What individual people CHOOSE to do with they vehicles is irrelevent and does not reflect on the vehicle's INTENDED purpose.
And no, I am in no ways condoning drunk driving. Like it or not, people have free will, and no matter how hard you try, some people will make absolutley STUPID decisions. But this does not define an entire community.
Um driving intoxicated is illegal, jailbreaking is not. What is "banned" is not the cars, its the alcohol.... so ... by your own logic we should make jailbreaking illegal!
The difference, you are hoping people gloss over, is that jailbreaking is NOT like a car in that the car can ALREADY be used to drive drunk, the iPhone cannot be used out of the box for people to steal apps.
