       CoBox is a project to enable p2p cloud infrastructures with different trust-settings. The project emphasises privacy by design and easy data governance. The aim is to enable data commons, while protecting against the worst societal effects of dataification and data extraction. Many of the worst effects of Web 2.0 can be traced to the business models of the corporations that dominate the Internet: add-based and financialised businesses where services are paid through people's attention and click rate. This creates a number of devastating knock-on effects, including mass surveillance, design and development efforts aimed at creating addictive behaviours as well as information echo-chambers, phycological and emotional feedback loops. The consequences are ripping through the social fabric of societies and scorching the nervous systems of our bodies. Instead of a drive towards incorporating all interactions and behaviours into data centres for commercial exploitation, the emphasis of CoBox is to enable easy, yet conscious data governance where only the minimal necessary data is created and stored. What might be the new forms of organisations that would emerge from such an infrastructure? And conversely, which existing forms of organisations, networks and companies might benefit from such infrastructures? And critically - through which kinds of economic arrangements might a cooperative p2p cloud sustain itself in the long term?
