FWIW, I don't know if OB is a ripoff, if in general its instructors have what here would consider a good background, but from the perspective of analyzing the specific event, these issues only seem tangentially related.

What we do know, is:

1) They walked out on their own power w/o injury.
2) They had some snags in their internal communication and/or planning.

Personally, I'd be more interested in information and analysis about the specific event.
