This is something that people without a manufacturing background often don't appreciate. Modern production lines are so efficient that it's frequently more cost effective to build all units of a product with the same hardware but disable some features in software. I first came across this 20+ years ago working for an office equipment manufacturer. We had to add code for the service people to enable a feature in the machine that was already present (and pretty expensive to build), but not turned on until the customer paid for it. I remember at the time asking if it wouldn't piss customers off to know that they were paying for something that was already installed, but it didn't seem to faze the Marketing people in the least. Then again, the buyer was someone in a corporate office who would probably never actually see the machine anyway.
