require the training data to be shared to prove it was never exposed to the original source
I believe there have been lawsuits which have already proven these models stole, and can reproduce verbatim, copyrighted material yet there has been little to no real consequences for the AI companies. So, if they can get away with that from companies that actually have the means to present a strong lawsuit, the chances of some open source author to defend their code are slim (very slim in my opinion)
