Thank you for you exhaustive answer. "After a lot of discussion on IRC channels, learning from the experts, and reading about open source licenses, I realized it is just simpler to take a well established open source license and use that for my projects." And I know it is easier, to just use a established licence. But if I would have wanted the easy way, I would have never started my project in the first place. It is kind of big. Maybe big enough, that I can risk some stupid laws in some countries getting in the way. But I do not like to adopt to stupid laws. I would like it the other way around. The laws should change that try to force making proprietary standard. That might not change if everyone all the time adopts to it. So I am leaning towards making my stand here. My country (germany) allows it, so I do not think I am in danger of being sued. There might be problems regarding collaboration later on, but this can be worked out, I hope. edit: apparently no, in germany you also cannot just release into the public domain. Great.
