An anonymous reader writes: As reported before on Slashdot, one of the most terrible sins on Wikipedia is to edit articles for pay, or otherwise violate the "neutral point of view" policy, per their co-founder Jimmy Wales. And yet, the Wikipedia-criticism website Wikipediocracy has recently performed a study showing that a large percentage of the Wikimedia Foundation's largest cash donors have violated that policy. Repeatedly, and wantonly. In short, they wrote articles about themselves or their companies, then gave the WMF big donations — and were not confronted about violating the NPOV policy. It reeks of outright favoritism. The first installment of an upcoming multi-part series discusses the co-creator of Cards Against Humanity, and his blatant editing of the Wikipedia article about his card game, followed by a $70,000 donation to the WMF. An honest donation, or hush money?
