I don't know why it's that fascinating. Lots of people think some amount of copyright is reasonable but that life of the author + 70 years is far too long.
Adobe didn't generate them. Someone uploaded them to their stock photos site.
Nor was their issue that the images were in the style of Ansel Adams, but rather that they used his name. That's not a copyright issue. It's a trademark one.
Exactly, nuance is important. Short term protections are good, but companies shouldn’t be able to keep works from entering public domain for decades on end.
I wonder if those are to avoid two of the big image generation controversies:
1. Imitation of artists' styles (Make an image in the style of...). The restricted styles are pretty generic, so harder to pin down as being a copy of or imitation of some artist.
2. It's cartoony, which avoids photorealistic but fake images being generated of real people.
Say more? it's just the media thing about intellectual property rights?
