How will community rifts be managed?

I was thinking about how community members can at times disagree.

Sometimes mods disagree.

Certain users may not want to be in the same community as others.

Typically in social media when this occurs, people create their own new sub, discord, Facebook group, etc.

But my understanding is that with Just About making new communities for the same game might not be straight forward.

So what will happen?

If it's felt that a certain group of users has more control or say over a community, how do we allow those who want a different community with a different set of rules and expectations set up in Just About... Or do we accept that they just might leave for a different platform?
