“…This inconsistency has been sustained on different occasions by the rhetoric adopted by the WhatsApp office in Brazil in public speeches in which it is emphasized that approximately 90% of the messages exchanged through the application are limited to interpersonal communications between two users, and that the average number of users in groups hosted by the service averages around seven individuals (D. Durigan, personal communication, October 27th 2020). And, although these data are replicated in studies that, having received funding from WhatsApp's own public calls, argue that research on the political effects of dysfunctional information sharing should not emphasize large groups dedicated to political discussion, since they would be the exception and not a rule, and would not reflect the experience of most users (Rossini et al, 2021), it is notable that the problem is not related to the interpersonal exchanges but to the virality of messages shared by and within these groups (Santos et al, 2019). Thus, ignoring the threat posed by end-to-end encryption applied to public groups with the participation of agents from the professional field of politics (Chagas, 2022;Modesto;Magalhães, 2019), is equivalent to color-blind the nuances acquired by the service by incorporating multiple affordances.…”
