Telling the Stories of Leaderless Movements

Often, the leaders of a movement play important roles in telling that movement's story. So in a "leaderless" movement, who gets to tell the story? How does the audience judge any narrative's authenticity or accuracy?

A couple of "leaders" I deeply admire in the Portland Black Lives Matter movement are Mac Smiff and Gregory McKelvey. Both excel at addressing tendencies toward absolutism and binary thinking among activists. This Twitter thread from Greg is a good example.
