Windies Abandon Indian Tour.

The West Indies Cricket Board (WICB) released a statement on Facebook  saying that Bravo had informed them "the players have taken a decision to withdraw their services for the remainder of the tour of India".

I cannot know all the rights and wrongs of this matter blamed on 'player remuneration' but for players to pull out of a tour en bloc seems unpardonable. What had India done wrong?
