Elon Musk turned down all shares when he left OpenAI because he believed nonprofits are not meant for self-enrichment. "The reason I founded OpenAI was because I was concerned, based on my conversations with Larry Page, that he was not sufficiently concerned about the dangers of AI. At my birthday party, he, in front of a large group of people, called me a speciesist, for favoring humanity over computers. So after that, I was like, We got to have some counterbalance to Google, because Larry doesn't seem to care if humans make it or not. So I thought, what's the opposite of Google? It would be an open source nonprofit, and that's where the word open, in OpenAI comes from. It means open source. I provided all the money, recruited the key people, and taught them everything I know. I actually even got them to deal with Microsoft. And for all that, I did not seek any financial reward whatsoever. The reason I actually took down the offer for shares is because, I mean, I felt like what are the shares, and why like nonprofits supposed to have shares? Nonprofits are not supposed to be self enrichment, so that's why I turned on the offer of shares." — Elon Musk
