IMO this confuses the right to distribute a work (patchsets already
provided) with the right to distribute entirely different works (patchsets
produced after termination of contract). Future support and maintenance
are just not part of a licensee's obligations under GPLv2, irrespective of
what theory of law you're applying.

As always, though, the only view that ultimately matters is the judge's.
