He's not going on about it, the media is going on about it. First they asked whether a new chairman of selectors changed his hopes and he said he didn't think it was entirely about selection policy. Then they asked him if he thought he would play while Clarke is captain and he gave another honest answer. It's not like he's rabidly running about shouting things, this was in a press conference. Since then, they've got a bite out of Clarke and one more from CA. He hasn't said anything else, they've just republished his comments, as well as the ones from June.
People say they hate it so much when public figures lie or "appear fake", but they hate it even more when they are honest.
