Rabbi Berel Wein served as Rabbinic Administrator of the OU’s Kashrus Division for five years (1972-1977) and left due to his growing cynicism about rabbis. Rabbi (J.B.?) Soloveitchik initially tried to dissuade him, but upon hearing Rabbi Wein’s true reason, he then approved of this decision, saying, “Cynicism is on the road to kefirah” (!).
Listen to Rabbi Shlomi Wise for yourself here (I may not have captured the nuances), minutes 6-9.
I think there are multiple lessons here, including for American kashrus (given OU’s size), the limits of reform, and the spiritual risk of cynicism.
Which reminds me: I know someone who once ate almost anything because he relied on all the various Hashgachos equally (עזוב, הכל סתם פוליטיקה). Then he went and studied to become a Mashgiach himself. For a few weeks or months during the course, he was far more aware. Now he is a certified Mashgiach… and he eats just about anything because he distrusts all the various Hashgachos equally!
(Yes, of course I tried with him! By the way, see this.)
