...דיני "חג שבדה מלבם" אנשי סטמר ובו ז' סעיפים

I wonder what the late Ponovizher Rosh Yeshiva would say about his good friend the Satmar Rov and the new "hag" that his Chassidim made. Is this too a חג שבדה מלבם? Is it as bad as י"ט כסלו? Are these הלכות as good as Reb Meshulom Roth's פסקים regarding saying הלל ביום העמצאות?
