DY -“The issur has nothing to do with who does the milking, as long as there’s no supervision, it’s assur (aside from the heterim which may apply in our times in the U.S.)”
To say in general it’s Assur, no matter what, Is Not true.
Many Achronim are Matter things like cheese, butter, etc.
Some say this applies to powdered milk also, like in the Dunkin Donuts. So acc. to you if it was Assur all the time, except for the US, how could they Matter these things?
So you see that Shittos held that CY was Not as Chomer as you’re saying!
