This is a false equivalence fallacy. Developers solve problems that businesses run into, whatever they may be, not just pump out code. Also, the solutions they come up with make use of a massive public domain of previously solved problems, like on stack overflow. If software had the same culture of copyright that music has today's technology would be equivalent to what we had in the 80's. The open source community is a glaring example of why you're analogy is so flawed, because there are many developers who believe open access to information is a good thing and that their skills are still valuable even if their work isn't copyrightable, and they do more than just believe this, they live their lives that way.
