1. I am not extrapolating anything. Everything I said was either straight from Rav Yitzchak Berkowitz’s Sefer or the Chafetz Chaim.
2. Rav Yitzchak Berkowitz is a poseik.
3. The Chofetz Chaim says straight out that you can only speak L”H about such a person if it is l’toeles and meets all of the other conditions of toeles.
4. I have no idea who Rav Binyamin Zilber is (which doesn’t mean that he can’t be very choshuv, but I have never heard of him and don’t know who he is). Whoever he is, his psak does not take precedence over the Chofetz Chaim.
5. You haven’t even brought his psak, so I just have your word for it that even he says that.
