A group of Chinese writers has nearly doubled the amount of compensation it is seeking from Apple in a lawsuit. The group alleges the U.S. tech giant has been selling pirated versions of the authors’ works on the company’s App Store. Apple takes a 30 percent cut from app sales on the App Store, which Apple has acted too slow to remove the pirated products, the group says. Apple has told the writers to contact the developers selling the alleged pirated books, but the developers often provide little or no contact information.”]
