Dissenters fostering changes across the world are often perceived as troublemakers and often pay a high price for their opinions or behavior. I want to tell a story of dissenters as important catalysts of societal changes. Societies require consensus as well as dissent, but the concept and characteristics of the latter are under-investigated. The theme has gained relevance in times of polarization due to new digital technologies, which can also increase the control and surveillance of people and change dissent, people’s interactions, and governance. The investigation examines exemplary cases in the light of one another and literature. The socio-legal approach includes the institutional treatment of cases under diverse regulatory models. The results shall contribute to advance rights and innovation in societies and help to solve controversies. Future works will be able to compare how institutions stifle or protect dissent, and secure or deny access to justice to dissenters.
