> Much like pitches from the Free Software Foundation of a world without copyright and IP.

If there exists no copyright, you cannot force an entity to release the source code of their software.

A world without copyright and IP is for sure an interesting thought experiment, but very different from the FSF vision:

In such a world, there would be much more reverse-engineering and monkey-patching of existing (non-open) software that gets copied around very liberally.

On the other hand, because there exists no enforcable copyright, companies would of course invest a lot of ressources into developing hard to crack copy protection schemes. Similarly, freedom-loving hackers would invest serious ressources into cracking such copy protection schemes.
