India is very corrupt but then all companies know that already. There is nothing special that Reliance can offer that Vodafone or Airtel wont. In fact during the Congress government India saw the largest scam ever perpetuated by non-Reliance players.
Reliance is also not a winner always. Reliance industries has burned its hands on retail, 2G services, agriculture, social media and many other business.
People assign too much competence of current BJP government. Had they been half as competent as their opponents claim we would have seen a far different India.
