Eida Hachareidis Ignore "Vayoel Moshe" Edict and Speak Hebrew

 The VaYoel Moshe issued a "Fatwa" against speaking Ivrit, however all members of the  Eida Hacreidis in Israel including the Raavid from the Badatz speak Ivrit all the time. 

Some of the rabbanim on the board cannot speak a word Yiddish and communicate in Hebrew.

In fact, most Roshei Yeshiva and Rabbanim give their Shiurim in Ivrit, you can count on one hand how many Roshei Yeshiva give their Shiurim in Yiddish. 

When they do business, Ivrit is spoken exclusively....even amongst Satmar chassidim ... 

This is a miracle in itself, as there has never been a case where an ancient language has been revived and spoken by millions..

This was accomplished in less than 100 years.
