My opinion, copyright has mattered very little in the corporate world. Copyright is effectively meaningless with SaaS, and the compiled software ran on your machine is protected more by technical controls and EULAs. A world where copyright didn't exist for software would look nearly the same for the commercial world. Trade secrets, NDAs, and employment contracts bind workers more than copyright. The only thing that the question of copyright has real world impact is open source, but even then only for more restrictive licenses such as gpl.
