Dear Qwerty,
I don’t understand your complaint.
There is the mainstream kabbalistic concept.
There is what the Rebbe said.
There is how it was understood on this thread.
I don’t understand. On which one Rav Moshe should have intervened?
He wasn’t going to publicly take a side on a kabbalistic debate.
Even if he knew what the Rebbe said, Rav Moshe wasn’t going to prevent the Rebbe from speaking about these concepts.
Rav Moshe is not alive to comment on this thread. These statements mostly entered the public Lubavitch discourse after Rav Moshe’s passing.
