It is quickly turning into one of these things that there are laws for, and everyone thinks it is rediculous, it is never enforced and DE facto not a law.
And what a shame that is.
US patent and copyright derive from A1S8C8 of the US constitution, "to promote science and useful arts".
Much EU law derives from a French tradition based on droight d'auteur, or moral rights.
International copyright code (Berne Convention) rips and mashes from both traditions.
Just as e.g. sodomy laws claiming that something is immoral doesn't make it so.
