Abstract
Investigations of data-centered efforts in advocacy and activism are often cast in terms of a narrative of opposition between grassroots activists working through and with data, and corporations or institutions whose actions data might expose. The boundaries are, however, not so distinct in practice. Indeed, one outcome of successful advocacy efforts for opening big data to the public is that the activists may find themselves drawn into the institutions they critique or view as impediments in order to actualize those efforts from the inside. Drawing on an ongoing ethnographic investigation of urban data initiatives inside city government, we explore the productive ambivalences of activism and advocacy that arise when those with data activist ideals find themselves operating within the government structure.
