What do the European AI Act, the European Commission’s Data Strategy, the proposed US Digital Platform Commission Act and the German Digital Strategy have in common? They all name the public interest as a key objective. For good reasons, it is increasingly en vogue for digital policy to be designed as to foster the common good and serve the public interest. But what should public-interest digital policy look like? Wikimedia Deutschland has developed eight requirements against which digital policy projects must be measured if they are to serve the public interest. Transparency and effective participation are needed. Fundamental rights must be protected and damage to the community must be prevented. Digital policy should mitigate inequality, its outcomes must be open and accessible, and it must be collaboratively managed and renewed.
