Agreed, but let’s also be honest about this:
The smaller, less visible alternative communities seldom grow. It’s the classic case of the biggest and oldest trees getting all the sunlight, while the saplings in their shadow are stunted.
We saw this on Reddit, too. Alternative subreddits, usually born out of protest of the moderation on the original, popped up all the time and never grew. Some did, some even overshadowed the original, but that was rare. The algorithm and search results would always funnel visitors to the old one.
Unless there’s an effort made to give more visibility to the smaller and less established alternative, there’s a good chance it goes nowhere.
So in reality the user choice you’re describing is less about choosing between two communities, and more about choosing between a community or a DND group that gets together once a week, but half the people flake out anyway.
This is why federation should have a standard that needs to be followed. Been saying that for a year now.
Instance level administration/moderation has an effect on the democratic system that is the backbone of the entire federation. We can choose not to federate all their actions, but it still has an effect on instance A when something isn’t visible on instance B and instance B visitors can not not vote on it. It skews the outcomes for everyone.
So there should be a standard for federated instances to administer and moderate fairly and honestly, in line with established and public rules.
