Harm is weird. If I sell bootleg copies of harry potter, I'm not harming anyone in any sense but opportunity cost. Sales that would have happened didn't occur.

Harm is weird. If I sell bootleg copies of harry potter, I'm not harming anyone in any sense but opportunity cost. Sales that would have happened didn't occur. The law sees that as harm. Personally, I'd like not have my IP used in training ML models. If they want to incorporate my stuff into their training data, they can do it on my terms, which would be either paying to license my work, or something along the lines of a new kind of copyleft license where the model has to be public and copyleft too. By including my work anyways, I didn't get the terms I would have needed. Scale makes it weird, because it's the a-drop-of-water-in-an-ocean issue, but harm is still real harm when it's split into a billion separate pieces of infinitesimal harm.
