The only difference
(that I can see) between BSDI and GPL software is that you can't give
it out to people who haven't paid their dues. This goes against the
anarcho-socialist principles that seem to motivate Free Software but
both models are pretty similar in practice.
I see another difference: BSDI will never be a "standard", where as
GPL, for all the anarcho versions that it spawns, will always be a
standard. Since the value of standards is so prevelent in today's
business climate, I believe that BSDI software is doomed to fail while
GPL code (or other free software) will continue to flourish.
