“Copyright” – i.e. deciding who can and cannot disseminate information is not only unsupported by human nature, human nature actively opposes it. Indeed we have had several million years of evolution telling us that it is a Bad Thing(TM) to not disseminate information we’ve come across. If some information is interesting, people will spread it. You do not, can not, and never will have control over information you release where many people can see it. Not while humans remain human.
