It wasn't dumb from corporate perspective, which is why they all gobbled it up like junky hoovering on piles of white dust.
You know how expensive it is to mold unique dedicated physical buttons for every function and then wire them all over the place? Or just slap single touch display and cram all the shit into that single display. You code it once and use it on all models. Corporates were already counting the money saved there. Until it backfired because everyone hated it, reviewers criticized it and now it's finally also criticized by safety agencies.
Not expensive. You don't have to "wire them all over the place", you just put them on a PCB and connect them to the nearest CAN bus, or similar.
One more connector, one more cable in harness, more coding, more cad time, more manufacturing time and more testing.
If it comes out to 20 dollars per car and you multiply it by 50000 a year for a relatively popular model there is a nice bonus for the ceo. Oh, and the price to consumer increases at the same time.
More coding?! Are you serious? Over a touch screen!
Also, extremely easy to test.
