I've been told by several independent sources that it really doesn't 
matter.

The "pure license" argument was born largely for silly reasons: people 
claimed (a _loong_ time ago) that the GPL wasn't enforceable in the US 
because in order to be enforceable, something of value has to change hands 
(in the US, for example, it would be common to "sell" something for a 
nominal sum of $1 USD rather than to give it outright, to "seal the deal" 
and make it irrevocable).

That's generally considered a specious argument, apparently. In most 
jurisdictions in the US, a license and a contract are judged to be legally 
exactly the same thing, and if you don't follow the GPL and have no other 
contract to show for it, you're in violation of federal copyright law, so 
whether it is a license or a contract really doesn't matter.

So it's true: the GPL just gives you rights, and without it you have no 
rights (other than fair use ones etc), and blah blah. But the distinction 
between "license" vs "contract" really isn't a very important one in any 
case.

I do agree that you can probably use this to say that the intent of the 
copyright has a stronger position, and that his "intent" thus matters 
more.

But I suspect that the "intent" angle is fairly weak legally to begin 
with, and if you cannot show that the intent was mutual, it's probably 
weaker still. So yeah, the intent of the copyright owner arguably might 
matter more, but quite frankly, I suspect everbody is better off not 
worrying so much about "intent", and worrying more about the "terms and 
conditions" part.

(I've said several times that intent _matters_, I just don't want people 
to think that it matters a whole lot).

What is pretty clear, though, is that the intent of a third party in the 
license/cotnract matters not at all. In the case of the kernel, the FSF 
being such a third party.
