How do you reconcile your claim with these sections of the GPLv2 and
v3, both referring to an executable or object-code form of the work?
GPLv2, section 3: You may "Accompany it with the information you
received as to the offer to distribute corresponding source code.
(This alternative is allowed only for noncommercial distribution and
only if you received the program in object code or executable form
with such an offer, in accord with Subsection b above.)"
...
Arguably the GPLv2 clause doesn't apply because Debian is typically
distributed with the source code available on the same "medium"
(server), rather than with a written offer to provide source code
