But bear in mind this criticism comes from Wikipedians – some of the people who actually wrote the encyclopedia you love, and did so for free – and it criticises Wikimedia, not Wikipedia. They are not the same thing.
Most of the Wikimedia executives are recent arrivals who only came once there was money. They have never written a Wikipedia article. Some can't even figure out how to leave a talk page message, and they couldn't tell you which side of a diff shows the new version of an article and which the old.
