Thank you for the link Noodles that is interesting and depressing reading.
In one way, it is an argument for paying CEOs of charities 'the going rate' to ensure that they employ someone with the necessary business acumen - but by the same token, if charities are businesses, they should be subject to just the same accountability and governance as other companies, and it seems doubtful that they are.
I support Research into Ageing, which originally was a small independent charity which funded very worthwhile research. it was subsumed by Help the Aged some years ago, before the merger with Age Concern, and I do now have misgivings about how the money is spent.
