Likewise I think it is extremely dubious that models can be copyrighted at all, for the exact same reason you can't copyright a phonebook or database. The entire regime of claiming to release models under various licenses is bullshit, because you can't copyright rote transformations of things either.
This is definitely going to be argued over in court at some point, along with many other questions about AI and copyright.
Speaking of which, why is it taking so long to get a supreme court decision on whether or not training counts as copyright infringement? The only court cases that have been resolved so far have settled on unrelated grounds without touching the core issue.
