Yeah, it is. It is for authors that got their works stolen for "the greater good" without even being notified. A friend of mine found his works in the Stable Diffusion dataset, the work was not meant for public use, he's never been notified and, most of all, he would have never agreed if they cared to ask. https://laion-aesthetic.datasette.io/laion-aesthetic-6pls/im...
That said, it did get a little better at drawing like your friend from that. But so does every other person who looks at his art. The model however might be better at it than most people. It's a dilemma but it's hard to say any individual image is "stolen"
We kinda already went through this once when GitHub scanned all public codebases to build the model for Copilot. When they did that, Copilot got the ability to program a little more like me (sorry everyone). But when I publicly put my code out there, I was also giving people the opportunity to learn from my code and reproduce similar things to it as well.
