Isamu Kaneko, the Japanese developer of file-sharing software Winny, died due to an undisclosed illness on July 8, 2013 at the age of 42. He was charged in 2006 with “assisting” Winny users to violate copyright, but the case against him was later overturned and his acquittal upheld by the country's Supreme Court.
Japanese economist Nobuo Ikeda (@ikedanob) commented in grief:
@ikedanob: Isamu Kaneko was epic innovator. If the Kyoto Prefecture Police had not regarded P2P with hostility, Japan could have been home to innovative business such as Skype. The nation state is incapable of generating innovation but is capable of interfering with it. My condolences.
