Your contract is worse than marriage (no divorce), and a terrible strawman. Lifelong written contract with a stranger? Ugh. What if I change my mind? I'll just continue releasing things permissively, and gradually abolish copyright in the process. (I don't really care about attribution which is generally all that's left.) You're free to use what I make in your copyleft projects!!

A deal is a deal. If you want to retain the option to change your mind and sue people over IP, then that is your decision. I won't be enabling that kind of behavior, nor will I donate code to it.

The best option would of course be that the law was changed and IP abolished by political change. Copyleft and permissive licenses would go away, artist could stand on the shoulders of giants without fear, and compensation would be addressed before the art was made rather than afterward. A fitting end to the flame wars.
