I think the marketing is targetting people’s percieved desire to know where they come from, (but not as far back as thousands of years ago).
Hence testing for ”ethnicity”.
If you tell someone they are 40% Scandanavian and 30% English plus a few exotic trace percentages, they can understand that, and have a bit of fun trying to work out where those percentages come from in their ancestry. It is DNA testing for the masses, something to discuss at dinner parties. Accuracy, or lack of it, doesn’t matter.
To tell someone that they are R2D2

is too abstract a concept, and requires research and study to understand. It can be complex to get your head around (more so for some than others).

Just my thoughts Gen.
