The claims made there are beyond absurd and based on a remarkable absence of anything resembling reason.
That's echoed by a surprising amount of people here.
If you wanna do good in the world, you can't just aim a bunch of money at a goal and expect the good to happen, you gotta get your hands dirty and course correct when your original plan turns out to be more harmful than helpful. I'm sure there are a lot of good intentions in there, but from the outside it's looking like the supposed rationality has been compromised by greed at the expense of the supposed altruism. As expressions of altruism go, EA just doesn't seem very effective.
