AI weights are not open “source”
The complexity described seems to be resting on the unestablished idea that weights are copyrightable in the first place. If they're not, then presumably "available weights", "ethical weights", and "open weights" are all the same: open weights. Either your weights are under NDA and presumably considered to be a trade secret, or they are public, and the words in your "license" mean absolutely nothing? That seems like a rather important point to bring up when discussing the licensing landscape for weights...
