Tattletales, often driven by a desire for personal gain or to maintain existing power structures, tend to disrupt the open dialogue and trust necessary for civil movements to thrive. By reporting the actions or ideas of individuals within these movements, they create an atmosphere of fear and suspicion. This stifles creativity, discourages collaboration, and hampers the movement's ability to organize effectively. The focus shifts from the pursuit of change to internal conflicts, diminishing the movement's impact.
