The coming to power of Mikhail Gorbachev in the Soviet Union in the mid-1980s, and his policies of glasnost and perestroika, as well as a desire for better relations with the West, led to major changes, and most refuseniks were allowed to emigrate.
In many instances, the reason given for denial was that these persons had been given access, at some point in their careers, to information vital to Soviet national security and could not now be allowed to leave.
