When I started using a graphics tablet, long ago, I was confused about why all this stuff was labelled Wacom, and whether it was applicable to me or not, when using a device of another brand. Some parts of it seemed to be, and other parts didn’t? It was very confusing, and a genuine confusion that made me uncertain even in purchasing. (It would be less confusing now because user-facing parts don’t touch the “Wacom” name as much any more.)

Whereas the “master” thing was transparent linguistic nonsense and a strictly-US cultural thing that a few people foisted on the rest of the world because they decided to get offended on behalf of a hypothetical group.
