That is not completely accurate.

There are a variety of views among the Orthodox. Because Orthodoxy does not see ancestral sin as an inheritance of guilt or a stain, the precise framing of the Catholic dogma really does not fit into the Orthodox theology of original sin.

What Orthodoxy has not done is proclaim it a dogma.

“But Orthodoxy does not admit in the all-pure Virgin any individual sin, for that would be unworthy of the dignity of the Mother of God." Sergius Bulgakov, “The Orthodox Church”.
