I don't care for his tweets or his political thoughts, but I personally think he has done more good through his companies than most others with similar resources. In my opinion, when Gates was still running Microsoft, he did considerably less "good" for humanity than Musk is doing now. And Musk's contemporaries (Zuckerberg, Bezos, et al) don't seem to be interested in doing much good either.

It's easy to be an armchair critic and say you would do more good if you had those resources at your disposal. But I will admit that I have never worked and will never work a quarter as hard as any of the names I've mentioned here. Despite my criticism of Gates, for example, he has done more good with his resources post-Microsoft than I expect I would have been able to do with the same.
