I haven't decided my opinion on this specific license, ones like it, or specifically around rights of training models on content... I think there is a legitimate argument this could apply in regards to making copies and making derivative works of source code and content when it comes to training models. It's still an open question legally as far as I know whether the weights of models are potentially a derivative work and production by models potentially a distribution of the original content. I'm not a lawyer here but it definitely seems like one of the open gray areas.
