So what do you want exactly? Do you want the fediverse to remain small and irrelevant forever? Or do you want it to grow and become the dominant space with more bad actors but more useful actors as well?

Because you can't have both, and you will always have more extremists and shitty views with larger groups. I for one think the fediverse is a better implementation of the social tech for pack of a better word, and would prefer its implementation over the closed wall implementation of non fediverse applications.
