Fediverse images & #alttext will certainly be scraped by groups to train their AIs on image-text correspondence. I'm sure it will be happening already. (Yes, many tools can already generate crappy alttext, but high-quality paired data is *valuable* in ML.) Thanks to the precedent set by #commoncrawl and #LLMs, our copyrights and licence terms will be ignored even when explicitly asserted. Case law is not strong enough (nor international).
