If we could clone the brain of someone I hardly think we'd be discussing their vast knowledge of something so insignificant as the NYT. I don't think we should care that much about an AI's vast knowledge of the NYT either or why it matters.
If all these journalism companies don't want to provide the content for free they're perfectly capable of throwing the entire website behind a login screen. Twitter was doing it at one point. In a similar vein, I have no idea why newspapers are complaining about readership while also paywalling everything in sight. How exactly do they want or expect to be paid?
There is significant evidence (220,000 pages worth) in their lawsuit that ChatGPT was trained on text beyond that paywall.
