@stella i very much* doubt that this is valid. so it might be a deterrent to a handful of people but other than that it basically does nothing. what would be nice to see, however, and what would be much more likely to be valid is awareness towards share-alike-type license, so not" all IP" and not "public domain", just IP that is a derivative of the content and also "some rights reserved" (but also it doesn't really matter anyways, see link below). but how to enforce, how to prove...

https://creativecommons.org/2023/08/18/understanding-cc-licenses-and-generative-ai/ in short: where exceptions by law already exist, a license (or otherwise restriciton) isn't going to do anything. also: share-alike does apply to derivatives from cc-sa content (the only argument that could maybe be made is that a derivative has to be creative work itself and that anything ai/llm generated is not creative work - which would be a slippery slope for ai/llm protectors but a fun fight to see happen).

*absolutely no guarantee for anything, i have not researched this topic enough, basically only for like five minutes just now
