So, I always invert the mouse scroll wheel on Linux now, because the Mac scroll direction just feels right to me. Which is sort of the problem here: macOS’s UI works really well if the paradigm makes sense to you and long-time Mac users often have the same problems “backwards” when they use Linux or windows.
Did it feel natural to you in 2011? It's not that old of a change. You can get used to it no doubt and I almost feel like it makes sense on trackpads but not so much on scroll wheels. Why fight 10+ years of muscle memory for literally no gain and a bunch of pain everywhere else?
