I'm not even sure if network weights are copyrightable independently of the code and data used to generate them. In my personal (not a lawyer) view, the weights of a neural network are the product of a mechanical transformation process much like a compiler or assembler, and we don't consider a compiled binary to have a copyright independent of its source code.
I still wouldn't notoriously try to violate a purported weights license, mind you, both because it's rude to ignore the authors' wishes and because it would not be fun being used by NVidia or any other deep-pocket AI company.
