If instructors are selling their students short by taking shortcuts then they shouldn't be instructing; they are not helping anyone. Diving is an extreme sport with many unforeseen variables probably more so then any other sport being "marketed" today and by not giving a student quality instruction you are adding more variables to the equation.
If you feel the people who you are diving with aren't up to your standard then don't dive with them. Dive with like minded people and take that out of the equation.
