I think the GPL and use of the code in mutions gives some rather absurd situations.
Assume that someone fires a cruise missile on you and that there is a GPL component in the cruise missile.
Further assume that the missile is a dud. Ain't you lucky?
Now, you have recieved a device with a copy of GPL software, and we can assume that you aren't part of the senders organization, so I suppose there have to be a written offer somewhere on the missile where you could ask for a copy of the software.
What happens if you exercise your rights? The GPL does not say that the sender can't send a commando team to deliver your code (and execute you) so would you dare to use the rights? (Incidentally I think it do say that they can't charge you for the commando team but that is not much help in this situation)
