Hi all,

Let me say that this email is quite pedantic. Treat this as a bit of
diabolical advocacy.

I don't think the FSF would see a problem with that either. What do you
mean by "he couldn't give it to anyone else"?

The GPL doesn't imply that "he must distribute all parts of the software
in source form": it's perfectly fine to distribute binaries and make the
source available on an FTP server somewhere, would you agree?

The original message said "someone downloads the code and changes it" so
these modifications would have to be under the GPL. If the changes
consisted of implementing a plug-in interface, it's possible that the
same person might also write a plug-in library that would not be covered
by the GPL.
