I felt this way as well (since the mid nineties) until a couple of weeks ago when I read _Social Architecture_ by Pieter Hintjens. It has a strong idealogical flavour. He stresses that you should focus on building a community, with the code and platform as happy side-effects of that community.

For that reason, you want GPL because it forces everything back into the community. He gives examples of a friend of his who slaved on a BSD project that got forked with the friend having nothing to show for it. And NT adoption of much of the code from the BSD sockets API.
