Because most people are not competent to judge the quality of two similar product does not mean they don't care about quality. They just usually can't tell, so they go for the cheaper (which has a higher probability of being worse). And it drives the prices down, and the quality with it. Or it reinforces monopolies, because only those who already produce at scale can produce better quality at lower price.
But if there was a way to correctly tell people: "look, this smartphone is 20% more expensive, but it will last twice as long and it will be more convenient for you in ways you can't understand right now", nobody would go for the worse quality, right? The problem is not that people don't care about quality, it's that they are not competent to judge it and marketing does the rest.
Then the article talks a lot about art. Interestingly, the author says "I'm pride to not understand art, but let me still explain to you how it works". And then proves it by giving contradictory examples like "people don't care about quality, they will just listen to ABBA or go to the Louvre". You have to not understand ABBA or what's in the Louvre to think like that.
So here is my rant: it's okay to be proud to not be knowledgeable about stuff. But then don't be surprised if people notice that you have no clue if you write about it.
(Yes, I noticed the irony of writing a pedant comment about a mediocre article that prides itself in being mediocre and criticises pedantry :-) ).
