Everything ISRO did is indeed justified, and seriously, I'm tired of hearing bitching about how it sucks. Why is it justified? Because it makes economical sense. Prem is a very expensive item, and the way ISRO did it is calculated the amount of the people that would leave for one person they forced to buy prem, and they mathematically found the best possible outcome with the highest amount of income for them as possible. SO for all those who are bitching and saying how ISRO doesn't even make money this way, they do. And more than before.
