Wikipedia

It bills itself as "the free encyclopedia that anyone can edit", and while that's true, reverting people's edits is really easy, and so is blocking users or IP addresses. Not everyone can do that. Who decides who can and who can't? Another hierarchy of privilege - which can be revoked if someone's decisions are deemed 'out of line'. It's reliance on "mainstream sources" further echoes the pattern of commercially-controlled media the world over, so Wikipedia is not as radically unbiased and fair as it purports to be.
