That's the thing though, this isn't really "free" software as much as open. NRK is funding it and created it for their use, that's cost money. They spent money on supporting the hardware they clearly had and wanted to for their production. Any other user with their own setups they want supported will have to spend money on developer time as well.
Indeed, people usually contribute to FOSS by supporting the authors group or nonprofit directly, and contributing features and bug reports/fixes.
However, from a maintainability standpoint it is important that a project solves their own needs first. The "eat your own dog food" advice is important, or groups end up fragmenting a project into every pet use-case.
You are trying to establish that the financial meaning of free software is the primary meaning, while the freedom aspect has been the primary meaning.

Free software "allows users to run the software for any purpose as well as to study, change, distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program."
