Ah, yes that too. I was thinking of the defederating with lemmy.world and sh.it.works when I was reading that. But Also, yes, they are likely moving because mod tools on the fediverse are a nightmare. Honestly, I see why the US Congress and major lobbyists want to hold service owners accountable for what their users post. Creating a platform for users to post whatever then not moderating it properly should be and I think is illegal in the USA. The fediverse at heart seems to be designed without any moderation in mind.
It’s less an echo chamber and more simply an attempt at creating an Internet community that doesn’t constantly argue or insult people. Where you treat people like they are smart humans and where others return the same assumption. All different opinions are welcomed. I know I hold a few strong differing opinions than the norm on beehaw and have always been treated with decency. Taking those same opinions in to lemmy general I’ve been called names and attempted to be invalidated instead of people trying to see a different opinion. So if anything it seems like lemmy general is becoming an echo chamber and beehaw is trying to be a respectful discourse community.
