Though “smooth scrolling” that interpolates between detents is a considerably different creature than “smooth scrolling” that tracks touch and has inertia resulting from it. The former is like nails on a chalkboard whereas I find tracking/inertial scrolling quite pleasing with how it lets one use muscle memory to “fling” the page to a particular point with decent accuracy.
Yet "smooth scrolling" is latency, and to most who are already used to scrolling, it is extremely unpleasant.
When one does scroll (i.e. move the viewport of a larger screen that's being presented through the inside of a window), it is because one wishes to already be seeing the target position.
Any latency through added animation destroys the illusion.
I quickly close any webpage that forces that strong discomfort upon me. And switch away from any application that does it against my wishes.
