I reject your statement about it not being ai resurrection, it absolutely is. 100%. you can try and weasel out of it by saying "Oh but they had another actor provide the base that the ai model ran against", it doesn't change a single thing.
In 2016 Disney released Rogue One, a film which featured a digital recreation of Peter Cushing, who had been dead for 22 years prior to the film’s release. Do you consider that more or less unethical than Miłogost Reczek’s voice being redone in the Cyberpunk DLC?
It's the same exact problem.
