@lxo I agree and share GPL values, but I just doubt the thought that it is a good idea to fight copyright with power of copyright in general. After some years of learning free software I kinda started to like the idea, that if you want to abolish copyright you don't need to be part of it, that's why I've started considering using CC-0 or moving software to public domain. I don't develop my own software for now, but if I would do it, I would consider between gpl and cc-0.
