Often – but not always – decentralised networks emerge due to a collective desire to rebalance societal power. One of the antagonisms that brought these tensions to the boiling point was the series of legal battles over digital intellectual property rights. This conflict – a so-called Copyright War – had started “offline” decades earlier, but collided with digital infrastructure for the first time in 1999 with the launch of Napster. Its trajectory would last over a decade and the fallout reverberates into the present. To understand the Copyright War is to understand how close copyright reformists came to dismantling an existing centralised data ownership structure, and how they failed to appreciate the resilience of this opponent as it economically and legally exploited their peer-to-peer model.
