this isn’t quite true. i was playing around with sd, and whilst browsing styles on a site where different artists’ names were compared using the same prompt (“[artist name] painting of flowers”, for example), a particular artist’s style stood out to me. i ended up buying a print from them.
sd might not directly include this info in its outputs, but it really is free marketing for some (in fact, i suspect a lot of artists are probably flattered for being included by name in the dataset, but some are riding the waxing wave of outrage for the free media exposure)
