“You just tap on it to focus where you want”
So what? You do that now with an android phone. The article implies something else that is not in evidence.
The “so what” ... ? Ummmm ... it’s in answer to your Post #5 ....
Exactly "So what?" are you referring to? If you are not happy with the default focus point the camera software has selected as the most prominent object in the center of the field of view, you can simply tap where you want it and it instantly focuses there. . . and you can select multiple focus points. The iPhone6 will select the most prominent point in the field of view to focus on, assuming that is what you intend to photograph. If it is not, then merely direct the focus elsewhere.
Exactly what are you inferring from what you claim the article is implying that is not explicitly stated?
