iacisrmma – their reasoning is fair, quasi-consistent, but wrong. Again, the reason a kashrus organization has a say, is their supervision — NOT their halachik expertise. My opinion on this website, is JUST as valid as their opinion on their website. Ask a rav. Agreed. Asking a mashgiach halacha, is akin to asking a shatnez “expert” whether you are obligated to check. Don’t.
JUST ASK A RABBI!!!!
(and if he knows his stuff he’ll agree with me…)
