Because DOS is an illegal copy of CP/M, but with a few features removed. And yes CP/M was way better, and had for instance multitasking way before MS-DOS. And it had filesystem safety, the lack of which caused decades of security nightmares on PC.

was cp/m really that good? never used it and all of the media I’ve seen of it looks like just another variant of dos. i grew up using dos, and I use the shell for a lot of stuff at work all the time these days, but i think most people prefer to interact via a gui

I think you mean DOS looks like a variant of CP/M, because DOS started as a clone of CP/M.
