Sabry, a political columnist for a number of Egyptian and international media, won praise for his balanced analysis even amid the deep polarization that has divided Egypt over the past three years, particularly after massive protests last summer led to the military's removal of Islamist Mohammed Morsi, the first elected president after Mubarak's fall.
At a time when many in Egyptian media were ferociously praising the military's move, Sabry while deeply critical of Morsi and his Muslim Brotherhood raised concerns over the possible return of a police state in Egypt amid a bloody crackdown on Morsi's Islamist supporters.
