Yes, one of the articles on HN a few days ago pointed out that a lot of the wealthy spend a lot of their time and energy preserving the social order. (It was a long article trying to predict what people will do when they don't need to work.)

To be quite blunt: I really don't think anyone who sells (or gives) IP to the general public has any right to control what happens to that IP after a fair period of time. That's why I say they're playing Calvinball: Changing the rules as they go for their benefit, so they can preserve the social order.
