What does Facebook get by plonking down $5.7 billion dollars for its stake in Reliance Jio?
Remember that Facebook owns WhatsApp
WhatsApp has 400 million users in India.
WhatsApp has been trying for a UPI license for some time now (approval for upto 10 million users in Feb).

Google Pay now has about 70 million users in India.
Financial data is the next battleground.
₹43,000 crores could be peanuts for Facebook to get this kind of reach.
It is 4 months of profits for Facebook.
10% of its cash on hand.
Without even a #privacy law in India.
