50/50 would be fixing a flaw in STEEMs implementation of game theory basics on the expense of the authors. It has to be modelled carefully with more variables. Also should a direct self-vote simply be filtered technically (yes I know that's easy to circumvent with multiple accounts). "Stakeholders" are not bringing the value in, content and the network effect does. The usual business model of just collecting delegations and selling the power to the highes bidder or running a witness without running a public node, too - that's scrounging on the network and nothing at all better than the big not-so-social networks do.
