Yes, this is very true. However, I would consider this to be a fork
from upstream. It's comparable to taking a binary-only module in a
GPLed product, reverse-engineering it, and writing new source that
duplicates the module's functionality.
What bothers me, though, is that the de-frotzed modules we create would
be derived works of the frotzed ones. Since, technically, "the
preferred form for modification" was never provided for those modules,
there's still some uncertainty. I don't know if upstream could exploit
this as a legal loophole in their original license (not in the GPL
itself, but in their use of it) and punish the people who did such a
thing. That, of course, is one of the reasons why I advocate caution.
OTOH, if our de-frotzed modules were licensed under the GPL, and if we
claimed there was an implicit exception to the GPL in the upstream
source, we could deny upstream access to our changes, since we wouldn't
need an implicit exception.
