Firstly the people running this are already incredibly wealthy by themselves. They more than likely funded the startup costs themselves, or through wealthy benefactors.

They pay operational expenses from a percentage of the money they raise.

Just because they pay operational expenses doesn't make them a scam - that's how any non-profit operates.

The best non-profits contribute the greatest percentage of their revenue to helping people. I believe this is the case here.

Do you want the best person running a company like this? Or would you prefer the cheapest person running a company like this?
