There are some issues here that I don’t quite understand. I just checked my container of Breakstones butter and it has an OUd. I then checked my package of Monterrey Jack cheese and it has an OK Chalav stam. Rav Moshe allowed Chalav stam.
My point being his what is gained by this monthly rehashing of the issue. Who cares what additives may or not have been added to the butter? That’s why you buy butter with hashgacha. People who eat Chalav stam will continue to do so as they don’t hold from the Nirbater Rav, and those who use CY will continue to do so. No minds are being changed.
