From https://www.cnn.com/2022/11/14/business/jeff-bezos-charity/index.html:

Amazon founder Jeff Bezos plans to give away the majority of his $124 billion net worth during his lifetime, telling CNN in an exclusive interview he will devote the bulk of his wealth to fighting climate change and supporting people who can unify humanity in the face of deep social and political divisions.

Though Bezos’ vow was light on specifics, this marks the first time he has announced that he plans to give away most of his money. Critics have chided Bezos for not signing the Giving Pledge, a promise by hundreds of the world’s richest people to donate the majority of their wealth to charitable causes.

So he made a vague promise, "light on specifics", that he would give away "most" of his money to fighting the climate change that is exacerbated by his lifetime's work and the social divisions that he has worked relentlessly to entrench? He could fight social divisions by treating his employees well and allowing them to unionize, but Amazon is notorious for mistreating its workers, it profits off forced labour in China, and he has fought dirty against unionization at every opportunity.

Forgive me for suspecting he's full of shit with his vague and noncommittal promise, after a self-serving lifetime of aggressively doing the opposite.
