This opinion betrays a lack of imagination.

There are two equally valid subjective choices here:

- does moving your finger up "grab the content" under the glass and move it up, or

- does moving your finger up "grab the window", moving it up along a long virtual document?

Both are legit mental models, it's a preference.

This would make sense if the choices were equal and opposite. They're not, though, since the advent of smooth scrolling.

how are they not equal and opposite?
