Rubin is someone who, from his days of running a BBS in New York many years ago, to creating and working to expand Android more recently, has always had a strong alignment with the values of free software, hackers and hobbyists. Over two decades ago he praised those who "write their programs for the hobby, for the hack". His commitment and his efforts for open source software and open platforms have borne fruit with an open platform which accounted for over 70% of smartphone sales in the fourth quarter of 2012. I am grateful for his efforts in this regard, especially since I have been focusing on writing Android apps for the past few years.
