They won’t need to, they will get it from Getty. All these websites have a ToS that make it very clear they can do whatever they want with what you upload. The courts will simply never side with the small time photographer who makes 50$ a month with his stock photos hosted on someone else’s website. The laws will be in favor of databrokers and the handful of big AI companies.
Anyone self hosting will simply not get a call. Journalists will keep the same salary while the newspaper’s owner gets a fat bonus. Even Reddit already sold it’s data for 60 million and none of that went anywhere but spezs coke fund.
Reddit and newspapers selling their data preemptively has to do with LLMs. Can you clarify what scenario you are aiming for? It sounds like you want the courts to rule that AI companies need to ask each individual redditor if they can use his comments for training. I don’t see this happening personally.
Getty gives itself the right to license all photos uploaded and already trained a generative model on those btw.
