I am not chabad and just reading the comments
Would anyone treat a Satmar this same way they are treating Chabad here
The Satmar Rebbe also had no children or grandchildren who survived him and the succession of Satmar has not been smooth either, so that Chabad has no Rebbe is not so far fetched since there was only one grandson of the Friderecher Rebbe and he is on the outs with the rest of Chabad
