The article doesn't say that a conspiracy within
Wikipedia tried to bias
articles. It says that a prominent industrialist and political
contributor
paid professional writers to alter Wikipedia articles to change the
descriptions of his involvement in a political movement.
It's a situation where organized professionals are working against
unorganized amateurs. If it takes conspiracies within Wikipedia to
counteract that kind of influence then we perhaps need more of them.
Actually, the editor was rather amateurish. I have some doubt this was
professional work by his firm that was paid for.
