More specifically Mao than the entire CCP leadership. The cultural revolution was an attempted coup by Mao to regain power after he was sidelined by his disastrous economic policies. It also really colored the viewpoints of the post Mao CCP leadership on populist movements. Specifically, Deng who was in charge during 1989 probably saw echos of the same students that exiled him into the countryside and crippled his son now marching again in Tiananmen square.
