That probably means they receive a lot of small donations. Payment processors often have a fee structure that's 2.9% + <flat fee around $0.30>. So any donation below ~$4.50 would end up having a >=10% processing fee.
There could be currency exchange rates that are factored in at the donation end as well.
I agree that 10% is high, but it's still explainable.
