Reading this, I finally got the idea I could unerstand what these ever lasting licensing discussions concerning open source are about.

Basically my vision would of have been the one of utter astonishment: Why and how could it matter? Isn't the whole fuzz about the licensing/copyrighting a clear example of 'If all you have is a hammer, then everything looks like a nail.' ? This response of me would basically focus on pointing out the absurdity in trying to messure the quality of 'modern' ideas with 'old and classic' benchmarks. (My -old- anwser by the way is of course far less argumenting then what Peter is offering)

All in all... In my head the decission for being an oss-believer-software-engineer versus a non-believer is pretty much based on the same obvious evidence as the "Why am I not a carpenter/birdwatcher/cook/lawyer/anythingelse ?"... If your lucky (like me), you'll find/create 'your' job so it synchonizes the most with having fun.
