@FediTips what you're describing is the average fedi enjoyer use case. Small communities that have at least one techy person able to do this on volunteer basis (but normally being a tech affine community in the first place). I think there is a limited amount of people in the world for which this use case works out. I would even say, it's not the norm.
You can (and should) have multiple smaller commercially driven instances competing with each other for te rest. But they need to start somewhere.
