Apparently, it was printed in or slightly before ??? ???”?, plus I gave you a link to a teshuva from an earlier chelek. Here are the key words:
??? ??????? ??????? ???? ?? ????????? ???? ?????? ????? ???? ??? ??? ??? ????? ??? ?????? ???? ???? ?????? ?? ??????? ??? ??? ??????
Loose translation with my emphasis:
If it’s very difficult to obtain CY, even individuals need not be stringent.
You can quibble with translating the words ??? ??? ?????? as “need not be stringent”, but it makes no sense to say that he meant it is assur to be machmir.
The evidence that his heter was for a “shaas had’chak” is overwhelming. In order to dispute it, you have to assert that the teshuva in ches is fraudulent, ignore the clear implications of the other teshuvos (especially the one I just translated), and somehow assume that R’ Moshe did not mean for the one which I originally posted to get out (which obviously R’ Forst disagrees with and you haven’t demonstrated any rov who holds otherwise). If that’s somehow the case, you have to assume that R’ Moshe’s reason for not wanting it to be publicized is that he didn’t really believe what he wrote!
