The initiative is called ‘Donor Revolt’. You can find it on

Americans are a generous people, donating billions of dollars every year to sustain a vibrant independent nonprofit sector. But as wealth has concentrated in fewer hands over the last forty years, philanthropy has become less democratic. Giving by low- and middle-income donors has declined while the ultra-wealthy have come to dominate philanthropy in America. The result has been less money getting to the causes that desperately need it.

Why does this happen? Because wealthy donors are more likely to give through intermediaries like private foundations, which are required to pay out just 5% of their assets each year, and donor-advised funds (DAFs), which have no payout requirements. This stifles the flow of funds to charities on the ground, preventing them from delivering their unique good.
