The problem is not really new. When the seventh Lubavitcher Rebbe took over from his father-in-law his mother-in-law was not supportive. When the present Belzer Rebbe took over, many Belzers followed instead his uncle. When Reb Yoelish of Satmar was succeeded by the next Rebbe, Reb Yoelish's widow was not supportive. I think the reason for the splits may be because there are now so many Hasidim that one Rebbe is not enough for each group. There is also more prosperity than ever before, so its easy to build competing structures.
