Apple's idea of "natural scrolling direction" is insane.
Scrolling with a touchpad and scrolling with with a mouse wheel are simply different things - the natural direction is simply different for both.
That’s 100 % subjective. There’s not a single reason why sliding your finger on a mechanical movable surface should behave differently than sliding it on a touch sensitive surface. You’re used to it behaving differently and that’s fine, but I prefer to have the same behavior for both and neither of us is right or wrong.
