I think a key word here is in the first sentence: "salaries". Love and money are the two greatest motivators. If you're really, really lucky you can find someone who will do something for love (first) AND for money (second). But the line quickly blurs. When faced with standing up for a principle at the risk of losing their salary, who will stay strong? It seems to me that all it takes is one senior person to be hired whose priority is money and the original loving intentions behind the founding of a charity can disappear like a puff of smoke. It's happened before. Anything can be justified and explained, anything. How to take the justifications and explanations depends in my view on how much money is being taken home by the person giving the explanations and justifications.
