There is no good reason to question Zuckerbergs&#x27;s motives. He very clearly means to donate his money to good causes over the course of his life.<p>Maybe it&#x27;s wrong for billionaires to influence the world as if they had billions of votes, but good or bad, anyone who questions his sincerity or general goodness is a bad judge of character.<p>And even if you can&#x27;t imagine Zuckerberg as a good person. Good luck trying to convince yourself his <i>paediatrician</i> spouse is not genuinely interested in helping people.
