In the context of the article, it is pretty clear that the author isn't asking whether Einstein was wrong per-se about special relativity; he is asserting specifically that Einstein was partially mistaken in his criticism of quantum mechanics and his dismissal of nonlocality (in the EPR paper). On the flip side, he credits Einstein for seeing through the smoke-screen put up by Bohr about separating physics from our conceptions of reality, that is, breaking the link between physics and metaphysics.
