> recommending that people choose dive schools that take their Job seriously and don't pass people who haven't mastered the skills

I think the point was that such schools get bad reviews, and look like bad choices, might get out completed by more lax schools

Apparently academia (universities) works a bit in the same way, there was a recent HN discussion

In my experience, I was able to fairly accurately glean a lot about the culture of a dive shop by the reviews it got.

I think that people often just go with the cheapest option without doing the additional research.
