Miliaku Nwabueze, a senior program manager at Code for Science & Society, had been concerned for some time about the role of technology in state violence. Then, on 7 October of last year, Hamas entered Israel, killing and kidnapping about 1,400 people. Less than a week later, as Israel ordered 1.1 million Palestinians out of northern Gaza in the onset of its deadly retaliation, Nwabueze decided to write a message to her colleagues on the US-based non-profit organization’s Slack channel.
