Think about patents. If you get a patent, you are legally protected from people stealing your patented idea for the lifetime of the patent. However, in exchange for that protection, you must make the idea public. In exchange for the protection of law, a patent holder sacrifices the protection of secrecy. A simmiliar model could be applied to copyright, in exchange for legal protections, you must forgo technical protections.
