And really, what is the correct incentive in terms of split?
Personally, I think each community should be able to change that spread as needed. Not sure if it's currently possible.
As for pessimism, I don't think so. I have decided to associate myself with communities I'm interested in, as well as taking moderation seriously. The communities that don't follow their own rules and visions, or the lack thereof, are destined to fail. Those who do may stand a chance to shine after the test of time.
On a side note, I don't think this should be tagged #stem or #steemace. Just saying.
