In 2020, she gave away nearly $6 billion to 500 organizations. And has distributed $2.74 billion so far this year to about 286 orgs. From what I've read, these grants/donations don't come with any strings attached unlike grants from a lot of big foundations.
To me, she seems like a really admirable public figure in general.
I do think that giving directly to individuals who will make sure that all of the money is spent wisely is an interesting alternative approach.
One of the challenges of this "pay it forward on steroids" approach is that it will likely be hard to attribute measurable changes to the original investments.
It does seem notable that Bezos has captured a huge set of resources, then paid it out to others for redistribution under their policies and procedures; he's essentially acting like a government which raises some concerns.
