Such schemes don't involve redistribution schemes that are based on the corporate shareholder model, as it is in Steem. The establishment and process of reaching the release candidate status will take money and time, and so naturally, this is a cost that investors will be bearing as part of their investment. The idea is that after the development phase is complete, from then on, the developers take a lighter touch to the system, and let it develop exactly how the users make it develop. There is nothing stopping individuals or groups forming to fund systems that interact with and add value to Steem, in fact, that's why I wrote this:
Steem is just the central component of an ecosystem that it aims to foster the development of. It is an accounting system and an investment system and a means for communication and marketing. Once the development phase is complete, this kind of activity will be far more important to the Steemosphere, and Steem itself will fade into the background as an infrastructure, not the core enterprise itself.
