IMO, it's pretty obviously all 3. Not letting people using the fruits of your labor (without permission), especially mental labor, seems like it's really akin to the right to privacy. That said, once you share something publicly, I think you automatically give up a lot of that right, and the law only protects against people making money on it directly. IMO, the question is: Is training an AI a direct use of that work, or indirect? And how does the law come down on that question?
