This chapter examines the transformation of the digital environment from the early notion of the Network Society to the contemporary Platform Society, arguing that this shift fundamentally reshapes the conditions under which political discourse on immigration is produced, circulated, and made meaningful. Moving beyond techno-optimistic perspectives, the chapter shows how digital platforms operate as infrastructural and economic actors that structure visibility, engagement, and data extraction through algorithmic governance. Within this framework, the chapter analyses key platform dynamics—such as algorithms, filter bubbles, echo chambers, and polarization —highlighting how they contribute to the fragmentation of publics and the intensification of ideological divisions. It further argues that the platformization of communication reconfigures the public sphere, displacing deliberative ideals in favour of affective, identity-driven, and emotionally charged forms of engagement. Finally, the chapter conceptualizes incivility and platformed racism not as deviations but as strategic and normalized features of digital communication, embedded within platform logics and reinforced by evolving forms of platform governance and content moderation.
