I think the real target here is still Gin. Not only for the reasons I listed earlier tomorrow, but also due to his long refrain from voting for Yoruichi. He wanted for a very long time and ultimately only voted for her per her request. He claimed it was because he wanted to "see how it would all play out," but even when he received much pressures, he stil refrained from voting for her after a long period time. Even after her death was all but assured!
