To be fair, Mukesh has got good connections everywhere. He is India's most powerful person.
Amitabh and the Shahrukh (some of the world's richest actors, both half billionaires) both volunteered as servers at his daughters wedding as a show of appreciation. If a man can command the most powerful of his country to such level of willful subservience, then every Govt. will try to curry favor with him.
I will add, that while his intentions might be entirely selfish, the pace at which Jio was able to bring affordable 4G to the whole country is incredibly empowering for rural / small town India.
That being said, adding money to the pool of what is quickly becoming a monopoly is not a "fund to digitize America" as Pichai put it.
