The gist of it is because there's some key features most don't have. This way they can offer something that's guaranteed to have it. I can't recall the exact details as it's from a recent Jeff g video I watched.

My work laptop is windows sadly. It has to run a bunch of endpoint sec stuff. I get it, but still sucks. On occasion I do dual boot (separate drive) when some update breaks something and I have to have a PC to fix something asap.
