Digital networks were built for the purpose of sharing computing resources by people who were themselves sharing resources, technologies, and credit in order to create it. This is why digital technology is biased in favor of openness and sharing. Because we are not used to operating in a realm with these biases, however, we oft en exploit the openness of others or end up exploited ourselves. By learning the diff erence between sharing and stealing, we can promote openness without succumbing to selfishness.
