Isn't that a valid worry? Especially in a project that needs user contribution the eventual horizon does matter.

Would you shovel dirt in a community garden project if you know the guy on top will eventually turn it into a commercial business? That means your work wasn't going towards a nice community garden as you thought, but it was going towards one guy being too stingy to actually pay labour. Sure maybe that guy didn't know he would do that from the beginning, but what difference would it make?

Governance does matter.
