"...share the voices between a larger group."
It is a common danger to be a victim of groupthink in institutional settings. In order to prevent that it is necessary to include people you don't generally converse with, to seek out and specifically include dissidents, those you disagree with, and particularly those that do not share the viewpoint common to your bubble.
It is notable that in science, every major change has come from outsiders, dissidents, and those that gatekeepers sought to silence. A patent clerk from Germany that barely passed university maths disproved Newton's physics, that had stood for centuries. Perhaps if physicists had courted more dissidents cosmology would have improved centuries prior.
Hive isn't as fundamental as physics. Hive can't last for centuries with the execrable user retention it has now. It should be very obvious that whales do not have the same interests as new users, so the mechanisms and principles they will propose and support won't reflect onboards and their needs. If you want Hive to grow - and unless it grows it will die - I strongly recommend asking users that fled the platform what it would take to get them back. I think I know what you'd learn from asking them, but I'd prefer if ya'll asked 1000 of them and learned it from them.
