R’ Moshe’s position was quoted in this thread. But the thing is that those quoting him, didn’t provide any sources and didn’t note that he discussed it multiple times, and he did not say the same thing each time. I have seen at least four teshuvos where he discusses it; there may be more (though I doubt it because the second one references the first one and the third one references the fourth one and the fourth one references the second and third and no others are referenced).
