and here (feel free to pass on to Chris):

1. I can see the argument about complex software products benefiting
from the BSD: at the same time I can totally see the value of just
keeping it open as well so everyone can benefit from improvements to
something that is as complex as Chris points point. Also if you keep
it totally internal to your shop, you don’t need to re-release,
although if you want to combine propriety and non-proprietary software
and then re-release I can see the value of the BSD code

2. When it comes to the question of ownership, where he says IP trumps licenses,
Chris Mackie does not seem to link the complexity of project to the licenses. When I was
having a discussion about this on Debian-devel, a number of folks
mentioned how very complex projects with many contributors, each who
had copyright and asserted GPL, worked through this swarm to protect
one person trumping ownership at some future point. They saw this as a
feature, not a bug, which I completely agree with. So some projects
are –and please correct me if I am wrong–far far more susceptible to
of weakness of the licenses if 1) they don’t hand over to a
trustworthy organization, like the FSF or the copyrights are held in a
few small hands. Once you start spreading the copyrights over a large
mass of people, it becomes very very difficult to ever assert a
copyright up and above the GPL.
