I think the winner here is pokerstars. As much as people talk about rigging for the sake of maximizing action, thus maximizing rake, this will probably put more people on tilt after seeing that they folded what would have been a monster. Personally, I'm indifferent to it. Once I fold, I don't care what I had, just as once I've folded I don't care what the board would come up as. Statistically, I knew the probability distribution for the board and decided against calling. Now I know this is easier said than done and I have used this a few times, but in terms of poker, this feature should make no difference.
