Wikipedia prides itself on being an encyclopaedia that is impartial. To that extent they do not permit anyone who moderators perceive to have a conflict of interest from tweaking and posting entries. However Microsoft has been found to try to do just that.
The software giant, had offered to pay a blogger to change technical articles on the community operated wed encyclopaedia. It was hoped that the link would not be found out and the revisions would be kept.
The pages in question, which Microsoft had hoped would be changed, revolved around an open-source document standard and a rival format put forward by Microsoft. A spokeswoman for MS believed that the articles in question were heavily influenced by people at IBM which favoured the open-sourced standard.
MS says this action was only taken because it had not made any progress trying to flag the so called mistakes to the editors of Wikipedia.
