I bet it has more to do with raising money.
The Community Advisory Board is supposed to take comment from the public about the station’s operations. At their last meeting the CAB groused that far too few members of the public come to their meetings. (With Gilmartin's appointment they may be on the verge of ironic solution.)
...it would seem that Ms. Gilmartin’s appointment to her policy-setting position on the WNYC board should be of vital concern to the CAB. To argue, contrarily, that it is only a board appointment and that the CAB should wait and be concerned only when station policy actually changes after enough board members of Ms. Gilmartin’s ilk have been appointed would be to say the CAB should react to close the barn door only after there has already been an irreversible escape of the horse.
