The article references the joint NPR/ProPublica report earlier this year, which found some pretty serious mismanagement of disaster donations after the major earthquake in Haiti a couple years back. One stat was that some 25% of donations went to internal expenses, and the report also found that the Red Cross diverted disaster relief resources to unnecessary places so they could appear on camera.
Small wonder, then, that Haitians are looking elsewhere. The article mentions a few places, but I wanted to add these that folks on reddit mentioned. Note that I have not done any due diligence myself.

I will say that the reddit comments claim that Hope for Haiti spends 96% of its funds on medical care (and only 4% for fundraising and internal costs), so there's that.
