That’s not true. I can ask ChatGPT for a verbatim copy of a licensed book. It’s been documented numerous times. I fail to see how, in the real world, a verbatim slightly changed version is different than a copy. But they’re selling ChatGPT, so effectively they’re selling access to libgen. So long as they can’t guarantee your unlicensed copyright won’t be reproduced verbatim, it is essentially reselling copyrighted material.
