Umm. I notice how you must have known how *idiotic* your response was, 
because you snipped away the part where I talked about Red Haty 
distributing CD-ROM's.

In other words, Red Hat distributes copies (and yes, you *get* that copy), 
and you cannot modify that copy that you got.

So the "right to make changes" _must_ be separate from the actual copy of 
the image.

And don't get fooled by the "all the rights that you have". That 
_obviously_ and clearly talks about "the program", which in turn 
equally obviously and clearly has to be about something bigger than the 
"one copy", since the GPLv2 requires you have the right to change it.

So you edited out the part where I talked about CD's. That's the proof 
that your reading is untenable, because obviously you cannot change the 
program on the CD: you got a copy, but the right to make modifications 
wasn't ON THAT HARDWARE.

Hey, I'm not exactly known for being polite. I tell it how I see it, and I 
tend to be pretty damn blunt about  it.

You keep on harping on that "modifyable", but no-where in the GPLv2 is 
that an issue. I claim that it *cannot* be an issue, since CD's are 
obviously ok.

So the "modifyable" part is a totally new thing to the GPLv3.

You cannot use that as an argument that the GPLv3 didn't change things, 
that's a circular agument: "the GPLv3 says so, so thus the GPLv3 is in the 
same spirit as the GPLv2". Doesn't make sense.

The fact is, the GPLv3 does fundamentally new things. Things I didn't sign 
up for (and things that nobody _else_ signed up for either) when I chose 
the GPLv2 for the kernel.

The fact that some people would like to change the kernel license to GPLv3 
is no different from the fact that some other people would like to cgange 
the kernel license to the BSD license.

Those people who have argued for using the BSD license, btw, argued so in 
the name of "freedom". No different from you. Do you think they were 
right? If so, why the hell do you think _you_ are right?

So here's what it fundamentally boils down to:

 - do you admit that the GPLv3 is a new license that does new and 
   different things?

 - do you admit that I chose the GPLv2, and have argued that I chose it 
   because I understood what it said?

 - do you admit that authors have the right to choose their own licenses?

And here's the fundamental answer:

 - if you answered "no" to any of the above questions, you're either 
   stupid (the first two questions) or a douche-bag (the third one)

 - if you answered "yes" to all the above questions, HOW THE HELL can you 
   call me confused, and argue against me when I say that the GPLv2 is a 
   better license? It wasn't your choice. 

It really is that easy.
