With these questions in mind, we began an observation of the communication activities of different social movements in Brazil and France 1 . Focusing on the agendas related to Covid-19, we began to collect and analyze clues (Ginzburg, 1980) from the observed groups, which led us to other groups, including the then newly formed Collectif Lyon Pour La Liberté 2 , whose actions were centered in the city of Lyon.We soon realized that the questions mentioned above, related to activism and communication and their intersections during the Covid-19 pandemic, began to worry us even more after a preliminary observation of the communication actions of Lyon Pour La Liberté. To answer them, however, it would be necessary to analyze the communication structure of the collective itself, which became our main objective throughout this research. And although we'll define communication structure better later, it's worth saying that we understand it as an architecture formed by media, interactional devices, and tools used in communication processes, taking into account the particularities of these uses.
