It's so obvious to me that machine learning models are derivative works of their training set. If they weren't, then why would these companies fight so hard to say otherwise? They need that training data to make their product, so they should pay the licensing fees for it! 10 years ago, when I worked on a machine learning model for my employer, it was unthinkable to train on data we did not have the rights to use. But now it's all fair game because OpenAI executives would make a little less money otherwise? They certainly aren't giving up any of their own copyright in return. It's a very transparent transfer of power and money from regular people to the bosses.
