That confused the shit out of me the first time I got a new Mac for work and the scrolling was all wrong. Best I can figure is that it relates more to touch screens so it may be more "natural" to people who grew up with a tablet or a phone as their first computer experience. As opposed to people like me who grew up learning how to use a mouse and keyboard as our first computer experience. Weirdly, I don't have the same issue when switching to a touch screen. I seem to be able to switch just fine. But on the computer, I have to switch to "inverted" even tho that's how it's been as long as I can remember. Well that's not true, I also remember having to click and drag the scrollbar before scroll wheels were added to mice 😂
