I don't get his complaint at all. In-game advertising is a cynical money grab and annoying to those who already paid for the game (obviously exempting F2P games). Having characters, planets, or other things named after the largest donors (without whom the game very likely would have never been made) isn't the same at all. I don't get his reference to socialism at all either.
