Now that Illidan is the big good leading Azeroth against the horrible Legion, isn't it a good time to also get back at Malfurion? I haven't exactly kept entirely up to date but assuming he hasn't, now is better than never. The fucking maniac imprisoned him, tormented him, and condemned him as evil almost all his life, and now that Illidan has everyone on his side, he could just twist a story around all this and turn them all against Malfurion.
But to my knowledge, that ever so satisfying moment to come hasn't happened yet. Why?
