I don't know if freeloading is the appropriate concept here. A person making open source contributions will be happy to see people use their work. They won't worry about whether the typical user also contributes back. Most people don't have the capacity to make such a contribution.

More broadly, the software industry "freeloads" over the work of all other workers who create a safe environment where food and energy is easily available. But the whole attraction of creating a society is to make life better eventually, otherwise we might as well have never left the savannah.
