Semantics....
Being certified to build ponds using AS products (skimmer, pump, biofalls) is not the same as running a franchised business where all elements of your operation are controlled and monitored. Once a pond builder is a CAC, they go about their business of building ponds. They may or may not stick to the training they received - some people are stubborn that way.
So how many of these CACs have you met you are giving out bad ecosystem advice? You said it's so many you can't even believe how many - that must be a large number. Or was that hyperbole?
