I think I've misunderstood the DFSG all along!
I always thought that the DFSG said a license could not restrict
the selling of the software, but it says:
The license of a Debian component may not restrict any party from
selling or giving away the software as a component of an
aggregate software distribution containing programs from several
different sources. The license may not require a royalty or other
fee for such sale.
I thought that restricting the charging of _only_ a redistribution
fee was not DFSG-compliant, yet this is what the Artistic license
5. You may charge a reasonable copying fee for any distribution of this
Package. You may charge any fee you choose for support of this
Package. You may not charge a fee for this Package itself. However,
you may distribute this Package in aggregate with other (possibly
commercial) programs as part of a larger (possibly commercial) software
distribution provided that you do not advertise this Package as a
product of your own.
I don't know why I posting this. Perhaps only because I'm
stunned. How did I get that wrong?
My question is: Isn't this a big restriction on freedom?
