A license may allow something but that doesn't make it ethical to do. At the time these licenses where written the wholesale pillaging of the commons by AI companies wasn't a thing. For that reason I don't think it matters what license anything was published under. Unless you where given permission by the author its not OK to train your model on it.
I consider Open Weights models only open in name, the training data is almost never released. As such it is just an attempt at open washing. Its like releasing some executable files and calling that Open Binaries.
