ETA: If you're complaining about use of the model, this becomes a dispute over how close to an original work an output can get before it becomes a copyright violation. That seems unresolvable. Look at court cases where musicians sue over short sequences of notes. Nobody knows where the threshold should be for that, for poetry, for flash fiction, for academic papers, for novels, for paintings, or for voice samples. Courts just go with whatever they think feels right in a particular case. That is an untenable legal situation in a world with AI models like these.
Also, to reiterate, Google has its own fulltext, license-free corpus of books, which it undoubtedly has used to train models. What's your view on that? Should Google be the only entity allowed to train on large books datasets because it happened to get one through a loophole of collaborating with libraries to OCR their collections?
