Well, i am not sure with your interpretation, but even if you where right, we
have no guarantee that A will continue being lenient, and no guarantee that A
will not start suing D or whoever for illegally distributing his stuff without
sources.

So, i get some random bit of GPLed software, i add a module or some code to
it, i distribute that code in binary format only, and claim that i have used
an hex editor to write it, or simply that it is the 'right' source.

I have some serious doubts that i will not get sued by all the authors of the
original GPLed work if i were to do that, and rightly so.

Even in that case, you still need explicit permission of A, and all the other
copyright holders of the rest of the GPLed work, to give you an explicit
exception to link with this non-free bit of code.

No. The source code is clearly the prefered form of modification, not some
random intermediate state A may be claiming is source.

The result is that the code in question has to be stopped from being
distributed by D. But the case here is different, since A is not the sole
copyright owner, so he doesn't get to set random interpretations of what is
source code.

Imagine A refusing to give away the source code, and D is ordered to remove
the incriminated code it is illegally distributing from all its servers, and
recall all those thousands of CD and DVD isos containing the code it
distributed, and being fined for each day it doesn't do so ?

So, we don't take the risk and don't distribute it. If A is not ready to put a
couple of lines of disclaimer on his work explaining the copyright and
licencing issues, then we are better of not distributing its code, which is
what debian will do.

Yeah, but who know what mad laws will be passed to repress piracy which will
make this void.

I am not sure. If i where to get a copy of windows, and manage to install it
without clicking on the "i agree" button, does that make it a legal copy of
windows to use ?
