I think you're conflating the notion of value and productivity. I'd argue value is far more subjective than productivity is. i.e. Facebook is maybe worth $200 billion today, but with a change in the market may only be worth $100 billion tomorrow. Whereas productivity (lets say some ratio of features, bugs, time) is more objectively measured and less volatile.
To be more clear: I'm not saying that they are reversing their "pick a patient" method. I'm saying that I saw how the "pick a patient" powered by the web model was an evolution among international aid / charity models. The "big generic fund" model however clearly is not. I'm not saying it's not convenient, I'm saying I don't see how going back to a model that's been used for decades is useful when such a model is arguably ineffectual at building deeper cross-cultural relationships. Not to mention that neither of these models of international aid or public health build anything sustainable.
How is this different from the typical charity/NGO donation drives of "donate 39 cents a day" ad? I saw how introducing personal connections to individual medical treatments was different from the norm, however this now seems to reverse that by going right back to the old school, typical, individual international aid style of monthly monetary donations.
