It does look from outside like "Ares Digital" is actually an add-on offered by an IT person as their personal project, and that the IT person does not necessarily want to do every possible labor associated with operating the studio, such as cleaning up any problem with the labels.
I do not know this is the case, but if it is, then a *competent* non-profit manager would know this situation innately. Volunteers who provide services may not want to do everything, and may promise to do so but not come through for whatever reason. Its not the same as an employment relationship. If something needs to get done, you don't leave it for an unreasonable time with someone who has offered but not stepped up with a solution. You monitor and respectfully make changes as required.
This seems like another example of Axanar trying to get away without buckling down and doing the work to get the results. Waiting nine months then blaming it on a volunteer and saying "I will just have to step in and spend money" is transparent, all right.
