If it's what I'm thinking about, I think they were forced to have decentralized image caching (i.e. the "user" is the one downloading images, Google just indexes).
LAION-5b is also just an indexer (in terms of images).
This argument's pedantic and problematic for artists; take away a human's "dataset" and processes and they are also unable to produce a single original "pixel".
