Working checkout doesn't prove a product is priced right, critic argues

A GitHub discussion exposed a gap in a five-question diagnostic tool for product failures, which classifies problems as traffic, activation, billing, or positioning. Reviewer chenhz01 argued that symptom-based classifiers can confuse adjacent failure modes, though the maintainer countered that the tool's direct yes/no gates prevent billing failures from being mistaken for activation failures. The reviewer's real point, the maintainer conceded, is that a product can pass the billing gate yet still be mispriced for its buyer, so the fix is a price change rather than new copy. The article notes that owners often reach for cheap messaging fixes instead of repricing, and that testing only with one's own purchases verifies the payment system but not willingness to pay. As a result, the diagnostic now explicitly flags mispricing rather than assigning it to positioning.
