Not really interested in arguing about whether or not she is giving her money away perfectly or to the best causes according to your (or my or anyone's) standards.

She gets credit from me for doing actual philanthropy instead of just cosplaying it for tax purposes, which has been the norm even for quite a few of the other "giving pledge" donors.

As far as bolstering government programs go, I'd love to see billionaires doing more in that area, but I'd also like to see us tax wealth properly to fund the government doing the government's job.
