I haven't read the article, so just speaking generally...

(and not meaning to contradict you, just thinking aloud)

I think there's some overlap between "taste" and "thinking for yourself" — though they are not the same thing.

Lots of people don't want to think for themselves in every teeny aspect of life, so choosing from a menu of "good enough" options is reasonable. It doesn't mean they lack taste, just that they lack the energy/interest/etc in that moment for that activity.

Another aspect: plenty of people will know whether they like something when they see it, but they won't be able to describe what they want beforehand. So, they have taste (ability to choose a good one), but not an ability to enunciate it, or conjure it out of thin air.

Also, the "taste" terminology is often intertwined with "style", and I think that's unnecessarily limiting. An "engineer's taste" might help them decide between gadgets and gizmos, based on their merits, even if they're both ugly.

To your last example, I think modern Lodge cast iron frying pans are mediocre. Not because of ugliness/prettiness, but because the sharp ridge/seam on the handle from the casting process is not ground down. It makes it uncomfortable to hold. Also, the cooking surface is left rough. Compare it to an old Griswold — miles apart, according to my tastes. They're both handsome enough to look at, though.
