In [my] ideal version of this, any monies made "down the line" from that open source software would feed back to anyone that helped build it. If 9 people contributed to a feature that a company used in their sales workflow, then each of them would get a percentage determined by the smart contract they reviewed when contributing.

If a founder came along and saw that a specific open source project could be the foundation for a business, then they could use it to build that business and feed back a portion of all profit as an operating expense. Then everyone involved would be benefited by contributing.
