That whole paragraph in that section of the article is more than a little contentious myself and a number of editors have removed it altogether in the past, while I believe it is plausible the citations often rely on "inside knowledge". Believe it or not the reference to the news article is the best form we have. I will get in contact with CCP, and see if there is a mechanism where non-registered users can see that news item. I believe that the polices say that requiring logins should be avoided, then again it is little different from citing a scientific journal or a newspaper that would require you to subscribe to an on-line database or buy the journal/newspaper. I will have another look tonight to see if I can improve the situation.   (Talk to me!)
