I love me some FOSS but I don't think that helps here, does it? In the end the person having domain knowledge is no longer in control of the process, because its been transferred to an automated system. Therein lies the issue, even if the software can be modified it cannot be done by the domain expert, or on the fly, or at low effort.
A FOSS system could be changed by the beurocracy in a more straight forward manner than a procurement circus with the copyright holder of the software, is my reasoning.
