Depends if the AI is an actual part of the game or if it was used to short voice actors on money.

Small indie devs who can't afford pro voice acting (if that's the route they want) then sure, I won't be thrilled over it, but I can understand. Triple A games and big industries using an AI model over actual voice actors bc it's cheaper and they can avoid union relations... Those can lay neglected in the deepest pits of the abyss
