The problem is companies externalising development work on the boring parts of their software as "community edtions" and the like. That is a very distinct category of open source project and the only one that any of these discussions revolve around.
You seem to believe that all open source projects are in this category. That is not the case. You also seem to believe that there is always one company doing the most work and everyone else is just leeching off. That is also not the case.
