According to the DFSG, requiring that you get permission to do anything
with the package is non-free by the very definition.

The thing about not entering it into contests? If the license said that
the program's origins may not be misrepresented, it would be free. It's
the requirement that you get permission before you do it that makes it

By design. The fact is that your pet package was rejected by Debian as
clearly non-free and as a result you feel it necessary to troll about how
the GPL is evil and so's the DFSG as a result.
If you can't understand the difference between the restrictions in the GPL
and the restrictions in crafty, there's nothing I can say that will change
anything. You're either unable or unwilling to se a difference between
one kind of restriction and another. The fact that the difference is
codified in the DFSG causes me to question your understanding of it. If
you don't understand it, I have to question what NM was thinking.

None that you'd be willing to listen to.

I flatly refuse to get into an argument quibbling over the spirit vs. the
language of the DFSG.
