Yes, it's Apple being Apple. They tend to favor compatibility with their own ecosystem.
Again, for touchpads, the default of natural scrolling matches the experience of touch devices such as iPads and iPhones. And that the "scrolling" on an Apple Magic Mouse mimics what you'd get on a touchpad.
It's a fair argument that the default for a traditional mouse with a wheel should not be natural scrolling. But it's understandable why Apple chose the defaults the way they did. And it's interesting that Windows (at least for touchpads) and Linux now offer the option for natural scrolling, so it can't be all bad.
I'll admit that natural scrolling on a mouse seemed decidedly un-natural at first after years of X11 on UNIX/Linux and Windows. I've gotten used to natural scrolling to the point where it's muscle memory now.
YMMV and I respect your opinion. Religious wars never turn out well for either side.
