I don’t know that much about aether, but I have a hard time imaging a voting system of governance that can’t be gamed.
True decentralization is nice but not a big deal for me. Given the open nature of Lemmy, the bar to moving instances is significantly lower than leaving Reddit. It would of course be very inconvenient, but so, it sounds, is aether.
Ultimately, to be accessible to average users, you need some amount of centralization it seems. Everything else is pretty science-projecty.
If you could migrate a community from one instance to another and have subscriptions update automatically, it makes the rogue instance admin a little less scary. But still a risk of course.
Not for nothing, but pork bun has been great for me.
