This is provably false. I live in an area where a lot of people are struggling because of Covid-related lockdown, and there are a number of small charities coordinating food and other donations. None of them are publicity machines, except in a very minor informational sense, and all are effective locally. That stops being true above a certain size - specifically when a charity adopts the tropes of corporate culture and starts spending more time on "messaging" and "engagement" than delivery. Inexplicably this seems to coincide with a hugely overpaid CEO and managerial staff. I'm sure someone like Bill Gates can afford to compile a global index of tiny all-volunteer charities and donate significant sums to them. But that kind of help won't have his name on it. It's not obvious it even interests him and his fellow billionaires.
