Why won't Chinese Pod make an official announcement about their move to Taiwan, and that Jenny and David are leaving?

Instead it is left to Jenny and David themselves to make a farewell at the end of a Media lesson, which most CPod don't listen to because it is well beyond their level.

How about keeping everyone informed for once. When are you moving, why are you moving, and who made the decision? (in fact, who is in charge of CPod these days?)
