I think you are confusing organizations and companies. Yes, under capitalism, companies only exist to reek in profits, but from a non-profit organization you'd expect something else...
Stakeholders include employees, and it is all organisations.
NGOs and government organisations follow the same pattern. They all expand, hire, and the people within each org all have a vested interest in the organization expanding and keeping them all employed, given raises, etc...
Sadly, the "companies only exist to..." version of capitalism is about as accurate as the "Santa only brings presents to Nice little ..." version of Christmas.
Substantial Organizations - whether capitalist, non-profit, or other - give a great deal of power to their leaders, and jobs to their workers. Those folks - most especially the former - may give lip service to the org's supposed mission...but their for-sure #1 priority is looking out for their own interests.
