Copyright law should be enforced, but it also needs to be reformed. The current expiration time is far too long. The idea that books and music of the 1920s-1940s are not yet public domain is absurd.
Quite right. It used to be 14 - 28 years after the author's death. The notion being that was enough time to protect the livelyhood of dead author's family. Thanks to huge corporations like Disney, copyright has been extended to ridiculous terms, now 90 to 126 years. As much as I detest the information wants to be free movement, information should not be locked up forever by a handful of mega corporations who can afford to buy enough Congressmen every time their copyrights are about to expire. The balance between the rights of the author and the public good should ends at some point near the author's death.
That said the literary and music world is far different than the software field. Lit and music generates revenue for an author for a lifetime. 14 years after publication should be more than enough to protect software authors reasonably.
