Daas: Since the cholov akum makes the utensils treif (as you’ve said), how does even aino ben yomo help?
I never said the cholov akum makes the utensils treif, I said it in a general sense; I would not call cholov stam treif. Besides the fact that there is more than one legitimate heter to rely on, R’ Moshe, although recommending one be machmir, clearly writes that one who relies on it is not a “m’zalzel b’issurim”. I dare say that referring to “cholov stam” as “cholov akum” degrades R’ Moshe and anyone who relies on the heter.
how does even aino ben yomo help?
Because b’dieved, an aino ben yomo does not make the food ossur, because the absorbed flavors become “pogum,” bad tasting.
How can (some) people who are makpid on only eating CY, not be makpid on the utensils (considering the above issue)?
Either because we assume that the keilim are aino ben yomo, or because they only accepted CY as a chumra, and excepted keilim. I don’t understand this second approach, but it seems to be common.
And are you saying you can eat pareve food made with dairy equipment together WITH your fleishig meal, or only 5 minutes after your fleishig meal?
It depends on whether the equipment was ben yomo or not, and, if I recall correctly, whether it’s in your mouth at the same time.
There is also a distinction between if the food was intentionally made to be served with fleishig, which is why I originally limited my response to manufactured items.
