No, I know many authors do not want to release their artwork and data to the public, that is correct and so they should free to do so (only US people, the others (i.e. european) are not allowed to) and licence it under the ABC licence.
Thats not a great problem. I think, however, that there is NO reason why a contributer schould not use his own graphics in his own game or other games if he wants to. Actually, you cannot forbid this if the author lives in europe because it is simply not allowed to give away the copyright and as author you have always (at least until 70 years after your death) the right to do anything with your creationships, and thats my problem.
I can only repeat what I have said: Of course Atomic Blue can tell the truth and the game stays free but why the hell should they then reap everything away a nice man has done to let the project benefit.
* The materials will only be used in the PlaneShift game (or its successor games created by Atomic Blue) and not in any other.
* The materials, once contributed, will be retained by Atomic Blue no matter what might happen with other projects, forks, mergers, alliances, and Atomic Blue will control how it is used.
And at last, I don\'t believe in goodness of any concern any more. The lines above are so clear there\'s nothing to add more.
After Atomic Blue has got enough data, they will do the following:
Sucessor game = Commercial game based on non-open-source code
GPL-based-game = Server is closed (nobody is allowed to set one up so nobody can use it)
==> everybody who contributes to this project is in risk to contribute to a cash-greedy concern, this game is not open source
Nobody can tell me such licence restricions are only there for nothing but the benefit of the community. This licence is more restrective than the privacy terms of ICQ which allowes them to do everything they want with the data of the fobbed artworker/scripter.
I suggest to reread the licence, it\'s dangerous.
