> The New York Times article cites Stanford University law professor Mark Lemley, who disagreed that generative AI services violate copyright law, and intellectual property attorney Bradley Hulbert, who said a new law might be necessary to settle the question of legality.

> Months after Balaji's death, which attracted significant public attention, Hulbert told Fortune magazine that Balaji's essay "[reads like] the argument of a really smart non-lawyer who read up on the subject but does not have a thorough understanding".

If there's some kind of industrial-scale intimidation campaign that's stopping IP lawyers from litigating the case of their lifetime, that's an even bigger story than OpenAI taking out a hit on somebody. It seems like they're agreeing that the copyright abuse was never hidden, and it's sufficiently transformative enough that nobody could argue it's illegal.
