Corporate greed, that and there voice actors probably feel there jobs are threatened. Seems like a good add-on. Guessing to the devs don't want players questioning them as to why this isn't in the game already. I mean imagine if the devs actually had to do work instead of delaying things "cough"flying" . Imagine having all npcs read the quests for you instead of you having to . That would add to the immersion.
