=Rybka Controversy= Chris Whittington was and is critic of the arguments that Rybka is a derivate of Fruit since Zach Wegner published his first conclusion on the Rybka/Fruit: evaluation in June 2010, and consequently critic of the ICGA decision in 2011. During the Investigation process, he was rejected to become member of the panel.
