Earlier quoted context omitted.
That's not the point; once released, why should people not be allowed to freely copy and share it? Why do you think you get to control what other people do with information?
It's not only about copying and sharing, but also who has the right to sell and distribute. If you create software, you are copyright owner of that software, which means I can not take it, sell it and take credit for it. I don't think I get to control what other people do with information, but you should have the right to control what others do with your work.
Ug.. it's pointless to state how things currently work in a meta discussion about whether the current method makes sense.
I'm asking you to justify copyright, not explain it. I repeat, why do you think you should get to control what other people do with information?
> I don't think I get to control what other people do with information, but you should have the right to control what others do with your work.
And I say you shouldn't, so justify your belief. You should be able to control yourself, that's it; not the products of your labor when copied. Information is not property, you don't have less of it if I copy it and you should have no say over me copying it regardless of who produced it.
