Yosi. Wait. I must be very dense today.
It appears to me you are saying essentially:
I have reliable sources that tell me they heard directly from Rav Moshe’s son that Rav Moshe actually held directly opposite to how he poskened in his seforim. That he wrote these false psakim so that he wouldn’t be criticized.
And that you believe your reliable sources that this is (or is even remotely possible)the truth.
Are you saying this??
