From the quotes in the article, I have to agree with drawing that line. On the one hand, making a non-profit mod using AI-generated voices has no opportunity cost to the actors since they wouldn’t have been hired for that anyway. On the other hand, and this is why I am leaning against training AI voices off people at all without permission, it can cause actual harm to the actor to hear themselves saying things they would otherwise be offended by and wouldn’t ever say in reality. In other words, the AI voices can directly harm people (and already have, according to the article at least).
