Even with the 'value add' of the update, I no longer play the game. Why? Because I invested in learning and mastering the game as it was when I bought it. The forced update removed all value for me, and I'm the one who made the decision to buy it.
If the product is changed significantly after purchase without my consent, then I feel I should be able to revisit my decision to purchase it. Otherwise, it's a sort of bait-and-switch scheme.
