"Dictatorship" is the standard forum design. Reddit, HN, X, Lemmy... All of them. And censorship is common. We literally prefer it that way. I think it's to create a solid blame trail. I think that's a necessary thing.
But what we prefer and what's good for us are two drastically different things.
I actually do the opposite now. The second something aligns with my own ideals perfectly, I inherently distrust it. Because that shouldn't happen. We all think a lot alike, but also very differently. If any political party, commercial, or anything meant to be absorbed by the masses seems like it's perfectly aligned with you? It most likely is bad for you, in my experience.
to hear it from the mods, it's about being responsible for what's said to the admins above. so that's why they need to have censorship power.
"We literally prefer it that way" might apply to you and your bubble, but there's more outside of it.
