Rabbi Kaminetsky-Rabbi Greenblatt Heter: Rav Dovid Feinstein says it is worthless

Matzav  just published the following letter from R Sholom Kamenetsky acknowledging and accepting that Rav Dovid Feinstein's beis din had declared the heter totally worthless. He also indicated that his father has already stated that he would accept the ruling of Rav Dovid Feinstein.

Unfortunately I have not seen the psak itself. It had been expected that Rav Dovid Feinstein would reject the heter - after all it was obvious that it was a sad joke. The question remains did Rav Dovid Feinstein criticize those who had said the heter was valid? In addition will Rav Nota Greenblatt accept the psak? 

Without the criticism of those who produced the heter and without the retraction of Rav Greenblatt - the heter now becomes simply a dispute between poskim and Tamar obviously will chose Rav Greenblatt. 

Of greater importance, without the criticism of those who produced the heter  and its retraction - the heter will remain a viable option for all those who want a quick and simple end to a marriage without having to worry about the Get process. All they need is to pay a therapist to declare their husband to have an incurable personality problem i.e., to certify they don't like them and that they can do better with another husband. The therapist doesn't have to even waste his time talking to the husband - he will simply accept what the wife tells him.
