Are you an idiot, or do you just choose to ignore all proof that doesn't 
fit your preconceived beliefs?

The GPL doesn't give someone distributing the software the choice of how
much to limit the freedom of the user.

Either private keys required to run the kernel on the hardware are 
always considered part of "the complete source code" or they are never 
part of it.

Harald is in Germany, and he therefore takes legal action against people 
distributing products violating his copyright on the Linux kernel
in Germany at German courts based on German laws.
