As others have explained, paying for programming doesn't have to
mean royalties per copy. Quite a few who make money with programming
free software are probably in this list, so making such a broad
statement in public, telling us that it's impossible to do what we
just do, seems a bit silly ...

There are many cases of GPL-dual-licensing. One of the most
prominent ones is Perl. As I saw your directory on CPAN, I thought
you might have known that ... ;-)

What is true is that a recipient of GPL software can't redistribute
it under another license without special permission.
