It’s a bit disappointing that in articles like this there’s relatively little discussion around what organisations receive the money and what impact it has. We should ultimately judge people by that, not abstractly by “charity == good”? If a billionaire donates millions to the Against Malaria Foundation I would judge that differently than a donation to an art museum in a developed country - and I think people should, and it matters morally.
The difference between for profit and non-profit isn’t really important either compared to “what concretely did they spend money on and what does that plausibly achieve”.
(Tbc some cause areas he donates to are explained, and they seem reasonable and close to his life, but unfortunately not in any depth).
