Can you explain how that's expressed in the GPL? Is it the section I asked about, so the GPL's "convey the machine-readable Corresponding Source under the terms of this License" is your "[source] code that is as GPL as the [object code] they originally got"?
Alternatively, maybe it's section 4
> You may convey verbatim copies of the Program's source code as you receive it, in any medium
Which is a bit strange, because it's granting you a licence on something (the source code) you haven't necessarily actually got yet, so normally this grant of license would live with the IP it actually applies to. But I understand why it's necessary for the GPL to work in a more complicated way than that, because its purpose is to be viral and to bind the recipient to granting the same license when he distributes modified versions.
Your question doesn't make sense to me. You keep going off on tangents about possible interpretations. Can you go StackOverflow for me here and provide the minimal complete form of your actual question?
