On your instance too others are contributing the content, not you as a mod. Humans regardless of hierarchical or anarchical systems are the community. It's the gathering & exchanging. It's not the king paying for a feast that makes the guests mingle & communicate with each other. That's just infrastructure. If they go away to anther party there is no content there, unless the kind posts for themselves.
But are you saying that owning the server makes you own whoever donates their content in a discussion just bcs they have a systemic power?
I don't think people are generally confused at all how hierarchical online platforms are. Why would they be?
