There was some initial confusion regarding Apple's actions, as the writer of the article accidentally misinterpreted Apple's actions, stating on his Twitter feed that Apple was suing Wired. This turned out to be wrong - Apple only contacted Wired via a cease-and-desist letter. The video has been removed, but the article itself remains available. A representative said that Wired is currently reviewing whether or not to take down the article as well.
The article acknowledges that the procedure might violate Apple's EULA. A disclaimer reads: "Disclaimer: The following process potentially violates Apple's End User License Agreement for Mac OS X. Please ensure you own a copy of Mac OS X Leopard, if you wish to follow the procedure." The article links to torrent site The Pirate Bay as well.
As always, Apple refused to comment on the case. Wired's editor-in-chief Evan Hansen told ZDNet "we made a determination that the video... We're more comfortable taking down the video. [Wired tries] to default to the most conservative position we can in terms of removing content... But we don't want to pull content [needlessly]."
