  Privacy: An unnamed Jio executive mentioned “deep packet
  inspection” to Reuters, saying: “It’s called deep packet
  inspection, and what you can do with the analytics of that is
  mind-boggling,” he said, referring to a practice that digs into
  “packets” of data created by computers for efficiency, mining
  them for information. If this is happening and Jio is accessing
  data packets to develop patterns of user data consumption, this
  is a major privacy violation. The company deserves to be taken
  to court for this, as much as the India needs a privacy law.
