Says something when someone calls a 90 year old respected Rosh Yeshiva reform without even ensuring that he actually said what is being attributed to him. Sounds like someone needs to review the halachos of kabalas lashon hara.
Or that said Rabbi wrote a secret letter and let the while world keep on thinking that he approved it. He still didn't release a public letter.
The harsh letter is completely unjustified, but the Kaminetsky's aren't clean here.
