Or everybody could just be careful about not spoiling stories by warning there are SPOILERS AHEAD beforehand like we’ve been doing successfully for years. It’s much more simple than having everyone arbitrary deciding a a feature is suddenly old enough and they don’t need to respect it and its future viewers/players…

They are still selling the game, I don’t see why suddenly spoiling the story should not matter anymore. A little respect for people who buy it later should be expected.
