[Avodah] heter mechira produce

[SBA]

From: "Shoshana L. Boublil" <toramada at bezeqint.net>
During a discussion on another list, someone raised the opinion that
(according to him) Chareidim consider eating "Heter Mechira" produce like
eating Tereifot and Neveilot. I can't figure this one out.

When I asked a Rabbi from Machon HaTorah VeHaretz, he gave me source from
Chazon Ish and Rav Shlomo Zalman Auerbach that say that Heter Mechira
produce BeDi'avad are mutar.

Others too have mentioned that RSZA Ok'd people eating HM produce when
staying with those who use it. So I was quite surprised when I recently
received  a copy of the Torah journal Mevakshei Torah which reproduced a
poster from 5760 strongly urging full compliance with the laws of Shemitta
adding:
 ".vehinei kayadua ki lifnei keme'ah shana be'es dochek gadol shel pikuach
nefesh hayu migedolei Yisroel asher hitiru, kehoroas sha'a, lismoch al
hetter mechiras hakarka.

 - ulom barur ki bizmanenu hadavar pashut ubarur shegam hamatirim lo
hischavnu lehattir le'es kazos - ve'ein shum gemiras daas bamechira zu. 

Vehanosen yad lassos "hetter mechirah" - nosen yad laakor hamitzva.

Vedaateinu, daas torah, she'ossur lehistamech al "hetter" zeh - ve'ein
hadovor nitten lechilukei de'os ukehilos, vechol bar Yisroel chayav
beshmiras shemitta kehilchoso.  

Vechol hanosen lehoros lerabbim laakor shemitta al yedei ha"hetter"- gorem
chilul Hashem.."

Amongst the 19 signatories are Rav Elyashiv, R' Steinman, R' Wosner,
RC Kanievsky and Rav Shmuel Auerbach.

A bit strange that RS Auerbach would go against his father's psak?

Which reminds me seeing some time ago in RD Kohn's sefer "Ha'okov Lemishor"
(and I may have posted it at the time) showing how Rav Kook's teshuva
allowing the HM was based on a censored Chazal (IIRC) and the later correct
version makes his rayeh irrelevant. (I can't find my copy of the sefer right
now.)
