Bad analogy. I've already provided all the proof needed to prove that,
while "tivoization" may be against the "intent" or "spirit" of the GPLv2 it
is not in violation of it.

Okay. That means that if I ship Linux on a ROM chip I have to somehow make it
so that the person purchasing the chip can modify the copy of Linux installed
on the chip *if* I want to follow both the spirit and the letter of the
GPLv2. And no claiming that I'm missing the point - I'm drawing a logical
conclusion from your statement above.

I have no objection to this. What I object to is the manner in which it is
being done. However, I must admit that, at this point, I do not know of a
better method to achieve this goal.
