The survey asks whether people care about the headphone jack, though – it asks whether it's in the top three features they care about.

I care plenty about the headphone jack but still reluctantly bought a phone without one (which I regret) because I have more than three requirements to balance. I expect that the users who did include the headphone jack in their top three features still care that e.g. the screen, battery and radio are all in working order as well, despite not being in their top three.
