Especially considering that the advantage gained by having an AI sound like this one individual is absolutely minimal. It's not as though any significant portion of a target market is going to throw a tantrum, saying "No, no, I refuse to accept this simulated companionship unless it sounds exactly like the voice in that one particular movie several years ago." Baffling that the company didn't recognise the risk here and retire that voice as soon as they were turned down the first time.
