I frankly don't care how you label the game, Mesmer. Call it what you will. If you don't like the term Open Source, don't use it. If you have a moral problem with dual licensing then don't play it.
I'm also sorry that there has been so much arguing about this sort of thing surrounding PS. Many fans and others trying to help PS have done 90% of that editing and censoring. I have argued till I was blue in the face with several of them, trying to get them to stop. Many have heard me do it. The only good PR for the game is to make a good game. Splitting hairs about what label goes on what piece doesn't prove anything and probably only hurts our reputation.
Having said all that, I've been contributing code under the GPL for 8 years to this game. 10's of 1000's of lines of code. All open source.
What has been your contribution to the OSS movement? From whence does your sense of moral righteousness come? I'm not questioning it--I'm just wondering why people get so passionate about this when they really have no stake in it whatsoever.
