It's quite obvious that data is what pays the game. A lot of data about the players )daily routine, commute to work/school, social circles to other players, etc. which allows to derive Job, wealth, etc.), data about surroundings (where do people actually walk, drive, ... etc.)

The story here however I'm not too sure about: Isn't the game mostly played in dense urban areas? - by the time you need military drones there the area will have changed a lot (destruction, fortification, ... and overall be outdated) where I think the civilian drones (delivery, cars, ....) benefit more. While the technology certainly is dual use.
