There was vehement opposition to the revisionism of Pietism just as there was with Hasidism. In fact opposition was so strong there are records of Jews reporting fellow Jews to Muslim authorities on the ground that they were practicing Islamic heresy. David Maimonides brother of Obadyah and his heir was eventually exiled to Palestine at the behest of other leaders in the Jewish community. Eventually Pietism fell out of favor in Egypt as its leaders were exiled and Jewish immigration into Egypt slowed.
