Because it's better to run an unpatched OS (considering installing updates on a hackintosh tends to break it) than to run an OS with some pre-installed software that you won't even notice?
I meant that I run on a Macbook. I was comparing Windows with MacOS. Btw, software that I won't even notice? I paid 2.5k on a laptop that I keep docked most of the time, so I guess I do notice it, along with all the other things I've mentioned.
