The publishers' brief, made public in a less\nredacted form on Sept 17, leans on internal documents to argue that ChatGPT and Copilot substitute for news sites (the fourth fair-use\nfactor, market harm). On Oct 16 more of the motion was unsealed after publishers and Bloomberg Industry Group objected to redactions.\n\nGap: the dataset missed the Sept 17 filing.
