Friend that's an IP lawyer had a rant that copyright law is applied for things it has no business being applied to. The law is built around single author books and sheet music. Where the authors lifetime output is small. And commercially valuable work smaller still. Not appropriate for things like ad copy, manuals, and software. It needs an overhaul. But the current system heavily favors entrenched interests so won't happen.
