I do not believe they have shareholders. Afaik, the company business model is around providing tech services for humanitarian aid institutions and at least some revenue comes from that type of donor funding
If they don't have money for buying proper productive equipment, but spend what they have in unproductive ostentatious stuff for management, they are very likely defrauding somebody. It may be shareholders, donors, tax-payers, or somebody else, but they are hurting somebody.
It is also almost certainly not the employees (unless it's a cooperative).
