It may seem to you that en.wikipedia is totally devoid of this sort of systemic bias, but in fact no Wikipedia is.
This was not my argument---my argument was that systematic bias can be minimized on Wikipedias which are in languages for which a diverse body of speakers exists, but is unlikely to be minimized on Wikipedias in a language spoken by only a small and homogenous group of people. It may not be eliminated on any, but it will be much less severe in languages with more diverse speaker populations.
The current en Wikipedia does not have solely contributors from English-speaking countries either---there are a large number of English-as-a-second-language contributors who contribute valuable information and viewpoints. Our Beijing article has contributors from Beijing; our Gdansk article has contributors from Gdansk; and so on. This is very unlikely to happen in languages which are rarely learned as second languages.
