You’re either being intentionally obtuse or disingenuous. If there was a microwave or refrigerator out there that ran Linux for its components, you wouldn’t count people who bought that refrigerator as Linux users, would you? If anyone did, it would be to artificially inflate the Linux numbers since users only use the refrigerator/microwave functions. If they’re not exposed to any operational functions of the OS, then counting them as users of the OS is dishonest.
