If a frum jew says its kosher, then its kosher. When the O-U gives a heshcer on twizzlers then its kosher. Its funny how the term “chovevil Mafia” is used to pay the workers a fair wage, but dont use a similar term when there is an extra sticker on the twizzlers.
Either the O-U is a good heshcher or its not and personally Id trust the o-u over anything else since its so large and has alot to lose if anything is found to be a problem.
Restaurants cannot afford to be in business if they need to pay 3 Mashgiachs, they are expensive. If there are 3 hashghacha, 2 of them are the mafia.
