As a discipline and a set of practices, technical communication focuses on designing technical products through the effective implementation of usability to facilitate users in performing tasks with speed, accuracy, and satisfaction. This article proposes that designers in the Global North should consider the effective localization usability implementation in their products or systems so that social justice can be promoted in the Global South’s countries that import such products from the Global North. Using a purposeful sampling research method, this article shares findings from a study, emphasizing that technical products developed through participatory localization for usability might be in a better position to be used for promoting social justice and human rights in resource-constrained settings. The article discusses the implications of the findings, suggesting that northern products should be designed according to the usability expectations of local users in the Global South so that the North–South divide can be, at least, narrowed, if not eliminated.
