Are you confusing copyright with patent rights? Patents have a dual purpose: - they force exclusive access to a technology for a while, promoting innovation and profit; but! - they also force you to publish all the internals of how that technology works, promoting production of cheaper copies after the exclusive period has passed. I'm not aware of copyright having any such function.
