It most stuck out to me when the article talked about car colors - most cars are black or white because car makers mostly make black or white. Buying a car with a splash of color is hard. Red is your best chance. Followed by butt-ugly blues.
You cannot meaningfully choose according to your taste because choice is restricted. (Related, try to buy furniture that isn't a fucking cheap imitation of mid-century modern)
And that happened because offerening the most bland and inoffensive looks will be bought by the vast majority of people who don't care about taste, or don't have any. (How would you develop taste if all the choices are the same)
It's bland things for bland lives reinforcing more bland choices in product design. Mixing all colors gets a dull grey, and that's where we're landing.
