Not sure why Kittel is being accused of being disloyal when he could have left them years ago. Kittel did much more for Giant, than Giant did for him. He would have been a star on any team - being comfortably the fastest guy in the world. However, until this year, he was the only truly world class star that Giant had. He was the name that was attracting the co-sponsor - which was changing nearly every year and he was basically the one rider that allowed the team to become a viable World Tour team.
Then, when he went through his first period of poor form/injures, they dropped him from the TdF team, replacing him with several riders that had no hope of doing anything. An out of form Kittel still had a great chance to win one of the flat stages if he was delivered close to the finish - it was a ridiculous decision not to take him and suggested something going on behind the scenes.
It seems to me like Giant were fairly content to move Kittel on once Degenkolb made the step up to become a global superstar this spring.
