Imagine that Louis takes the $280k and buys a yacht. You may not agree with Louis that a yacht is a particularly worthwhile use of $280k, but the effects of the purchase are localized: Louis gets a yacht, the yacht company gets $280k. Conversely, charities are designed to have broad effects on the world. Often these effects are undeniably good, but not always! Some charities give out bibles, some campaign for the right to abortion, some campaign against abortion, some give food to the poor without regard to local economies, and some campaign for free software. I challenge you to find any one person who agrees with all of these things :) Now, I don't believe that the charities that Louis has chosen are doing bad work! But if you are going to be donating 28% of someone's purchase to charity, it would be courteous to explain, ahead of time, exactly which charities are going to benefit -- because not everybody is going to agree.
