Microsoft, Sony, Samsung, Apple, Deere, Caterpillar, auto makers, Airbus, and Boeing all are examples. Opaque error codes are a key element in the commercial success of the Windows ecosystem. A huge number of IT support staff with certifications in Windows admin are paid to do many trivial tasks because they were taught to deal with opaque error codes. The same staff recommend Windows to management even when there are much better solutions to a problem with linux or macOS. It also explains why Microsoft often makes gratuitous tweaks to standard protocols. -- George N. White III
