From what I understand, the problem with gates and other philanthro-capitalists is that they have the power to shift focus of organizations (research and administration) from what’s actually needed, to their own priorities.
Ie giving money to malaria which is not a priority rather than NCDs, which are. The whole field then re-orientates itself, breaking apart public health long term objectives and priorities.
The consequences are catastrophic and very frustrating.
Mind you that’s the same gates which held back the tech world for at least two decades with his shity OS, so to protect Microsoft’s monopoly from open source and Linux.
But the world is trained to admire rich people no matter how empty or dangerous they are.
