No signal in audio electronics is too complex to be measured. As far a systems signal measurement, processing and analysis, audio signals are by far some of the simplest things to measure.
There is certainly no good will on the part of the cable manufacturers. It's simply business marketing. Yes, the "repercussion" is basically just people getting ripped off and not being physically harmed as through unsafe medicines being sold. However it's still fraud. The involvement of the scientific community is exceptionally clear and necessary in this discussion. You should consider the point of view from someone outside the debate, who may be considering a purchase. To them, having an objective viewpoint may be useful. As an example, I have told people shopping in department stores that they can find an HDMI cable online for about $5 instead of paying the absurd prices in the store. The response is always amazement and appreciation.
