This short working paper provides a critique of the smart city and the alternative visions of its detractors, who seek a more just and equitable city. Drawing parallels with data activism and
data justice, it is argued that two main approaches to recasting the smart city are being adopted: inverting the ethos and use of smart city technologies; and discontinuing and blocking their deployment. The case is made for decentring the smart city, moving away from the reification of technologies to frame and consider their work within the wider (re)production of social relations.
