How Einstein's Quantum Realism was First Rebutted

I did not know that the 1935 Einstein EPR paper was rebutted before Bohr:
It must be observed that Bohr article was not the first response to EPR appearing in print in the physical review. Arthur E. Ruark in a very short paper focused on the previous quotation of EPR and developed the strongly positivist conclusion (iii):
This [EPR] conclusion is directly opposed to the view held by many theoreticians, that a physical property of a given system has reality only when it is actually measured, and that wave mechanics gives a faithful and complete description of all that we can learn from measurements.
That is correct.

The above paper makes a silly argument that Einstein and Bohr were both wrong. It says:

Of course this was just the beginning of the story: In 1964 John Bell, based on EPR work, discovered his famous theorem ([3], chap. 2) firmly establishing that quantum mechanics (irrespectively of being complete or incomplete) must be nonlocal.
No, this is false. Quantum mechanics is local. The 2022 Nobel Prize went to Bell theorem experiments, and the citation conspicuously avoided saying that QM is nonlocal.
