Impressive.  I've always thought that copyright covered the literal
work, and not its "spirit" or ideas or such.  An interesting
consequence of this is that parodies are only possible if the parodied
part agrees to it.  Wow.  How did the creative communiteis paint
themselves into such a legal corner?

And - doesn't this mean that any program developed with Visual Studio
and requiring Windows to run, is partial copyright Microsoft?  It
seems fairly analogous to me.

Didn't SCO argue something like this at an early stage in the IBM
case?  That IBM had taken code that IBM had written for System V (or
whatever it was SCO had bought rights to) and ported to Linux?  So
even if IBM developed it from scratch, it was a derived work, and
distributing it against SCOs wishes would be a breach of copyright.
(IIRC, this was turned down or dropped fairly early, so I think it's
a fair assessment that copyright doesn't go this far.  The case was
(ended up) as a breach of contract issue, at any rate.)

Of course most would infer that.  A lot of people infer that stuff on
they find on the internet is theirs to use.  I'm not sure public
perception defines reality, though. :-)

I would hope that users who incorporate such a patch would be in "good
faith", and not liable for damages, but I also think that if there is
no explicit licensing, the copyright holder could require the patch be
removed.  (I may be totally off base here, but if not, this could be
an argument for the "pull" model rather than "send" -- "pull" would of
course get its changes from a repository that includes the licencing
information, the "send" is just the patch.)
