Philanthropy is a pr scam for billionaires.
It let's them doge taxes while feeling like they are doing good in the world, while using their money to cause more problems. That article is about Gates screwing up education systems while trying to 'fix' them, because he has billions of dollars while the people who actually have a clue on how to fix things do not. Look into the other actions his foundation takes and you will see similar patterns, from funding destructive agriculture to sourcing their funds from private prisons.
For the claim that Buffett is doing any good to the world, in his own words:
"There's class warfare, all right, but it's my class, the rich class, that's making war, and we're winning."
It feels so weird to see her character compared to cartoonishly evil ones like Darth Vader and the Joker. When watching the movie she is clearly a very damaged person, her character is tragic. The way she treats Gump makes sense, her culture is intensely ableist which combined with her trauma provides context to her actions. The idea that she is somehow a bigger asshole than a domestic terrorist with no concrete backstory, a serial killer, or even evil space jesus, is ridiculous. Frankly it reeks of casual sexism whenever I see people smear her, it feels like folks are either parrotting the opinions they found online, or never tried to understand her character while watching the movie.
