It's unlikely that model weights are even copyrightable in the first place, at least based on what the US Copyright Office has said in the past. In fact, it seems that even the outputs of such models are excluded from copyright protection, regardless of the skill involved in their production[1]. IANAL, but it's likely that the license documents attached to these large language models amount to little more than somewhat weak ToS agreements, allowing the distributor a bit more leeway in managing their legal/commercial relationship with users of said models. At the end of the day, though, this is all mere speculation. We won't know the truth until someone decides to burn the cash necessary to test it in court.
