I think there's a good case that it's transformative entirely. It doesn't just spit out NYT articles. I feel like saying they "stole IP" from NYT doesn't really hunt because that would mean anyone who read the NYT and then wrote any kind of article at some point also engaged in IP theft because almost certainly their consumption of the NYT influenced their writing in some way. ( I think the same thing holds up to a weaker degree with generative image AI just seems a bit different sometimes directly copying the actual brushstrokes etc of real artists there's also only so many ways to arrange words)

It is however an entirely new thing, so it's up to judges for now to rule how that works.
