>> consumer products don't disclose the basics of how they work to their customers

user manuals tell you how to do something, not how it works. E.G. a motherboard user manual tells you how to enter BIOS Setup, not how secure boot works; where to set USB power output in system power states, not what the power states are and how they transition.
