Take Taiwan as an example. In 2020, we open-sourced the mask supply system. Many people may not know this, but the opposition party at the time looked at the OpenStreetMap data and discovered that our distribution — which we believed was fair, in that everyone was the same distance from a mask — was in fact deeply unfair. Because in rural areas, ten kilometers might mean a three-hour wait for a bus, while in the city, ten kilometers is a ten-minute MRT ride.
