The closest thing to rationality content I can pull from this is "just because a thing looks good, doesn't mean it is good". However, the source page lists a grand total of one corrupt non-profit. You can find one bad version of anything, no matter how good or bad the whole group is. You could probably even find a hundred such examples, just from population size and base rate alone. Vox doesn't attempt to check if he is right, he doesn't even list a few examples. He just lists a single instance of a probably corrupt non-profit and, pleased with his own cynicism and insight, declares he they has found a pattern. This is a good example of what not to do, and an important failure mode to watch out for, but you are presenting it as though it were rational rather than a cautionary tale.
