Software has become ubiquitous, and emerging software applications quickly become part of everyday life. Despite its many positive contributions, software is often perceived negatively, for example when users worry about software-mediated surveillance, discrimination and manipulation. Software users regularly share their perspectives on ethical issues, discussing it online with international communities. Our goal is to fill current knowledge gaps about these perspectives and understand the distinct contexts of communities that hold them. We aim to structure the context that describes ethical issues in a knowledge graph, and deduce user’s stances towards them. We analyze how these perspectives change over time. Our work is meant to support software evolution by explaining different sides of ethical issues found in software.
