It was not "taken from him". He is not an Israeli citizen, and the criteria for Israeli citizenship are pretty clear, so I'm not sure why either of them thought this would work. @TAHbKA has been saying that Tobias would have to go with Zilberberg for a while nowSo the only motivation I can see he would have to leave the better partner and pair up with much worse partner would be to make sure he is on the team to Olympics. And that was now taken from him.
I hope all the skaters will work on basic K&C stuff in Hebrew in advance of the Olympics.
