Exactly, the Humble slider should mean the lowest but instead they get a whole 11 cents more than the Charity option, and 4 cents more than the developers. It's preposterous. When the sliders are that close, yet there's a whole 3% difference, it's Asshole Design. Obviously the best answer is to use some other service that doesn't even bother giving anything to charity at all. The good can get fucked, Perfect or Nothing.
