“Any group that holds a event against the wishes of the Gedolim”
That part isnt true as there were other Gedolim who were pro like Rav Auerbach and Rav Dovid Soloveitchik. Additionally that group considers their own leadership as the authority and do their own thing and dont care what Litvish/Yeshivish Rabbonim have to say on the matter.
