Eastern European regimes under Moscow were movement agents, not native developments.

Evidence

The Moscow-dominated Eastern European governments rule for the sake of Moscow and act as agents of the Comintern; they are examples of the spread of the Moscow-directed totalitarian movement, not of native developments. The only exception seems to be Tito of Yugoslavia, who may have broken with Moscow because he realized that the Russian-inspired totalitarian methods would cost him a heavy percentage of Yugoslavia’s population. — Hannah Arendt, The Origins of Totalitarianism, 2549
