Why aren't there more mice with 360° scrolling?

From what I can tell Apple's otherwise awful mouse is the only one that allows for 360° scrolling with two finger swipe motion. (Their previous gen mouse had 360° scrolling with a small trackball on top but it constantly clogged up with dirt.) It's really nice for scrolling over wide spreadsheets and other sorts of documents that take up a lot of horizontal space. (You can do two finger pinch to zoom also but it's not as easy as it is on a trackpad where you have more surface area.)

I currently use a Logitech MS Master 3S which has a separate horizontal scroll. I don't like x and y scrolling mapped to separate controls (it makes diagonal scrolling tedious) so I mapped that scroll wheel to zoom, and instead do 360° scrolling by pressing down the vertical scroll wheel and moving the mouse around; it works but it's a bit clunky.
