Thanks for all the info, but I think the question is still open: *why*
doesn't Tenuva sell salted butter made without shabbat milk in Israel? In
other words, what is cause here and what is effect? Is there some reason
why people who only eat Badatz don't eat salted butter anyway, so there's
no point in selling it here?
