If model weights become non-copyrightable, it'll lead to an incredible shift in the industry.
When model weights leak, anyone can pick them up and run with them. It's not like code, where you have to set up an entire bespoke infrastructure, microservices, data dependencies, etc. Models are crystalized, perfectly distilled functionality with a single interface.
You'll start to see more leaks, companies building off the work of other companies, etc. Part of me thinks this would lead to faster, more distributed innovation.
