You mean software freedom, I guess. Personal freedom is greater with BSD than GPL, and with public-domain software than with any of them. Personal freedom includes the right to sell software at $0.20 or $200, and the customer's right to buy it or not. For the record, I'm against software patents, but also against being forced to publish one's code, which incidentally maximizes personal freedom.

Yes I mean software freedom. Well, free software (whether it is GNU/GPL or BSD-like) allow you to sell it. But how could it remain free (as in freedom) if redistribution has strings attached?

This is the problem right here; you used a term without bothering to mention that you're using a very specific definition of that term. In your view "freedom" does not mean maximizing my rights to do things with the software; instead, it involves deliberately limiting my rights in order to force me to pass along (your definition of) "freedom" to others.

There are definitions of freedom, many surprisingly common, which do not include that little quirk, and you'll find that "give up some of your freedom for someone else's sake" is, to many people, like saying "pay higher taxes so someone else can benefit".

Just to be clear. From OSI (see http://www.opensource.org/docs/osd ): "1. Free Redistribution

The license shall 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 shall not require a royalty or other fee for such sale."
