> Their ambiguous goals induce politics. [...] This is the problem with religious organizations and ideological governments: they can't be trusted, because they will be captured by their internal politics.

Yes, of course. But that's because "doing good" is by definition much more ambiguous than "making money". It's way higher dimension, and it has uncountable definitions.

So nonprofits will by definition involve more politics at the human level. I'd say we must accept that if we want to live amongst the actions of nonprofits rather than just for-profits.

To claim that "politics" are a reason something "can't be trusted" is akin to saying involvement of human affairs means something can't be trusted (over computers). We must imagine effective politics, or else we cannot imagine effective human affairs -- only mechanistic affairs of simple optimization systems (like capitalist markets)
