The OU is by no means Litvish, nor of “excellent repute.” They happen to not be Chassidim (that’s for sure) and they have grown to be such a big hechsher that you practically couldn’t live if you boycotted them.
Otherwise, I agree with your post, Catch Yourself. I think Gadol Hatorah must have been sarcastic though. He usually has extreme religiously liberal views on news articles, so it wouldn’t really add up.
