Hillof beans, Rav Dovid Feinstein PASKENED it’s ok to drink cholov stam, even though the teshuvos of Reb Moshe ZT”L indicate otherwise. You can call Rabbi Frankel of the Agudah of 5 towns (author of the Yad Dodi of the psakim of R Dovid Feinstein ) to confirm. I posted the relevant quotes from another website earlier. This is not negating the fact that the pashut pshat reading of Reb Moshe ZT”L indicates that one should be machmir. Bnei Torah should be machmir, but those who aren’t are not Reshoim.
“Yad zorim” is a phrase I assume directed at the last volume of the Igros moshe, the one with the “Brain death” teshuva that Rabbi Fuerst from Chicago alleges is completely forged. You can download the shiur from Rabbi Fuerst from psak.org.
