This seems to me as a contradiction from what RMF wrote about CY milk there he said that if one never took on the “chumrah” – like it was put upon them from their family – then one can just start drinking Chala Companies.
Any thoughts?
CY isn’t based on old family minhag.
Perhaps if a few generations keep CY in the US, it can become a minhag, interesting question. I don’t think so, though – it’s based on how to interpret Chazal’s gezeira so is based on halacha, whereas gebrokts is a chumra to be choshesh for an unlikely event of chometz which nobody holds is meikar hadin.
