One thing for HN readers to note is that the article is intended for people in the Effective Altruism community i.e. people who are going to donate anyway, and are just trying to decide where to direct their donation.

If you're in the majority of the population that doesn't regularly donate to a significant level, then please don't let this article simply turn your internal "should I donate to Wikipedia" switch off and leave everything else as is. Instead, start treating the Wikipedia donation banners as reminders to donate to some charity that you feel is worth giving to. (The EA forums would likely be a good place to research that, as well.)
