Abcd2, my point is that he seems to be contradicting himself regarding their reliability.
There are two basic parts of kashrus supervision: halachic standards, and the actual implementation of those standards.
I’m fine with the idea of a hechsher having low standards, as long as they meet the minimum, and they’re transparent about it. Rebdoniel’s realization that their standards don’t meet his is actually something which I applaud. It may very well be that their standards don’t even meet the minimum.
My issue is relying on the implementation of whatever their standards may be. Tablet-K has a horrible reputation in this regard. Rebdoniel is, on one hand, acknowledging this, yet other than the specific halachic issue he has with their treatment of gevinas aku”m, he would eat from their hechsher.
Even if he’s discarded them altogether, he should have done so earlier based on non implemention (shoddy supervision and enforcement).
I don’t get his approach.
