Even if these conclusions are correct, they don't mean that "Einstein was wrong".
Physical laws are approximate descriptions of reality that are based on certain explicit or implicit assumptions and any conclusions that you derive from them are valid only as long as they hold. If Einsteins assumptions are proven to be invalid in certain regimes, it does not mean that the theory of relativity is wrong, just incomplete (as we already knew it was).
For example:
Newton's laws are not wrong, they just assume that your velocity is much smaller than the speed of light. If your velocity becomes close to light, Newton's laws are no longer valid and you must use Einsteins relativity. On the other hand, Relativity assumes that Quantum effects are negligible. If your system is in the quantum regime, these assumption no longer hold and you must use different laws.
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.
