Not every program has high board pass rate. I have heard of programs with board pass rate in 40s. I've heard of programs losing their ACGME accreditation. And I disagree with your other points as well, not every program serves a diverse patient population and offers great work life balance. That is why the term "malignant program" was coined.
The 50% fellowship match is actually pretty impressive for a community program in New York. What's even more interesting is that those who didn't go into subspecialty fellowship actually wanted to pursue GIM.
Firstly, it was partially meant to be a joke on how programs sell themselves to you. Secondly, I have not heard of such low board pass rates from any of my IVS and would have a hard time believing a program can keep their accreditation with such low scores. Lastly, I have no idea where you are interviewing to get these delusions from.
