I imagine 'behind the scenes' at most organisations is a nightmare. My experience of the folks at Wikipedia is that they are nice bunch of folks, achieving really amazing stuff with a minuscule budget.
Due to their non-monetary goals, total reliance on volunteers, and transparent structure, they are more like the UN than Google, which inevitably leads to weird arguments.
In 2013, Wikimedia got over $44M in contributions. I'd not call that minuscule. Of course, they have huge site, huge traffic, etc. - but that doesn't make $44M minuscule.
