As a result of the recent court case against the site, they’ve removed all torrents not registered on the site by the copyright holder.
Apple has now rejected an application that allows users to remotely manage the popular Bittorrent desktop app, Transmission. Why? Because sometimes people use Bittorrent to bootleg things. In Apple’s own words:
this category of applications is often used for the purpose of infringing third party rights. We have chosen to not publish this type of application to the App Store.
Which means, “we choose to tell you to go fuck yourself” if you’ve just wasted hours/days/weeks of your life developing an app only to have it shot down on a whim.
