It's really two different things. If using data to train is either fair use or not a use at all (I belive it is, it's for all intents and purposes the same as reading it), the copyright on the training data is irrelevant.

Whether weights can be copyrighted at all (which is the basis of these licenses) is also unclear. Though again I think they should be, they are just as creative a work as a computer program for any nontrivial model release (though really I think it's important to be able to enforce copyleft on them more than anything).

Also, all these laws work to the benefit of who ever has the deepest pockets, so salesforce will win against most others by virtue of this, regardless of how the law shakes out.

But then again, my program is merely reading these weights.
