Looks like Apple is the latest in evicting Wikileaks from their servers -- the briefly-available Wikileaks app for iPhone and iPad has been kicked out of the App Store. From the WikiLeaks App's description:
"The Wikileaks app gives instant access to the world's most documented leakage of top secret memos and other confidential government documents."
Basically the app was selling WikiLeaks content for $1.99. WikiLeaks and founder Julian Assange are quite controversial, but it's not clear if the app directly violated anything in Apple's TOS.
Developer Igor Barinov responds with the following official status update, showing that the app was indeed removed from sale.
