Perhaps Zuckerberg envisioned this funding as a stopgap or "leg up" type of assistance that would eventually go away when the communities could be more self-supporting. I don't know the situation on the ground there.
But it seems that most philanthropies, if they intend to establish something enduring, especially a school or hospital, that they usually have an endowment and a board that will be self-sustaining, and it is not dependent on the ongoing largesse of the philanthropist himself. That seems fraught with peril in several ways.
I hope that the beneficiaries of these schools were informed in advance that their ongoing existence was not guaranteed, so that they could make appropriate contingency plans. I myself have been involved in plenty of projects which depended on ongoing grant proposals, and therefore we didn't bank on future years until the funds were all in place.
