Maybe, but I think way more things would turn into web services instead of offline apps, and that that's where most of the resources would go. Subscriptions everywhere, and slow all-code-on-server interfaces. And there would be draconian contracts to try and prevent developers from walking out the door with the source code.

I think that's more or less happening with or without copyright. I don't have a single piece of standalone paid software installed on my computer (either it's open source and free, or it's something that connects to a service that I do pay for)
