Don’t read too much into those changes! I think I thought of which one to donate to as having a relatively small effect, since as you say others are looking to send their money wherever has the most remaining room for more funding. But we switched from AMF to MC after GiveWell’s 2019 giving season recommendations said “We think that Malaria Consortium’s seasonal malaria chemoprevention program can use funding most effectively in the near term.” Switching from there GiveWell’s funds was downstream from deciding that since we trusted GiveWell’s judgement here we should just let them allocate the money directly.
