Sportsmen are expected to lie and be diplomatic in India
In India many actors, cricketers and celebrities have a colorful life like Hardik Pandya, some of them are even worse. However no one will have the courage to be honest about their life, in india, the most valued quality is hypocrisy and the ability to tell lies. They will pretend to be very honest moralistic saints when actually they are involved in endless scandals
The cricket board must have realized that on the chat show, he only discussed his personal life, at a later date, he may discuss other confidential matters, so it was better that he was banned for some time, so that he realized the importance of keeping his mouth shut or telling lies.
It appears that most cricketers have a similar lifestyle, the book Reham Khan, has even more lurid details of an ex cricketers life and no action was taken, the book is freely available in India unlike the TV episode.
