I don't think Rubin was forced out because he was judged a failure. There's just no proof of that. Android had succeeded and under Rubin the team was doing great - except that there was a lack of tighter integration between Google's other properties and Android - Chrome for instance took too long to get on Android and become good. Same with other apps. As is evident now from how much progress Hangouts, Chrome amd ChromeOS have made under Sundar - he was well poised to lead a team that would have all these under one umbrella and Rubin apparently had other interests. So it worked out well for everyone.
