I think we lose sight of why “powermods” gained power: they built the big successful communities. Reddit was largely successful due to some fantastic communities being built up, and that takes work. We need that work on Lemmy just as much as we needed it on Reddit.
Yeah, it’s not ideal if a small number of people control a large number of communities but we should understand why they got there, and I think the structure of Lemmy is likely to make it a bit less prevalent.
