You're right about the compute part being wrong. I never said it wasn't legal, just that they took someone else's work to train it. I would hope that voice synthesis is illegal without permission from the voice's owner, but I imagine it is untested so far.

But it's not just about the popup - it 's more that when your work is fundamentally about using reusing someone else's character, it feels pretty hypocritical to be so focused on making sure you get credit.
