Logically, there is no reason to celebrate if "India" wins or to feel sad if "India" loses. All the players are playing this game to make money and become famous. They are winning (in either case, because they make a lot of money) and we are losing by investing our time, money and emotions into watching and supporting their efforts.
So, since India lost, Indians are feeling upset and are blaming the players. What else do you expect? They are too emotionally invested and are convinced that if "India" wins, they have something to be proud about. I feel similarly. But, if you think about it logically, there is no reason to either feel proud or dejected in either a win or a loss.
