If companies train on data they don't own and expect to own their model weights, that's hypocritical.
Model weights shouldn't be copyrightable if the training data was pilfered.
But this hasn't been tested because models are locked away in data centers as trade secrets. There's no opportunity to observe or copy them outside of using their outputs as synthetic data.
On that subject, training on model outputs should be fair use, and an area we should use legislation to defend access to (similar to web scraping provisions).
