Wikipedia might be resistant to government capture. But it's rather vulnerable to other forms of capture.

Having said that I agree that Wikipedia is a tremendous achievement, and despite the wards it's amazing that it works as well as it does.

If you permit me to go on a tangent: Wikipedia is also interesting as a test case for our definitions of (economic) 'productivity'. By any common sense notion of productivity, Wikipedia was and is an enormous triumph: the wiki models harvests volunteers' time and delivers a high quality encyclopedia for free to customers. By textbook definitions, Wikipedia tanked productivity in the encyclopedia sector because these definitions essentially put revenue in the numerator and various measures of resources expended in the denominator---and Wikipedia's numerator is approximately zero dollars.
