This, a lot of ppl talk about the pre installed thing but Linux has a lot of friction yet. Linux is big, it's open and made to run in almost any device with an arm or x86 processor, yet Linux is usually a pain in the ass on edge cases and we cannot ignore. Some years ago dealing with drivers on Linux was a hell, today is better but still has edge cases (this is not a Linux fault usually, vendors are shit usually but it cause friction. Audio just recently was resolved with the adoption of pipewire but pulseaudio had a lot of caveats. Now we are getting rid of X11 that is great for usual usecases but is full of workarounds if you want to to a simple thing like having two monitors with different refresh rates. There is a lot of things but linux is going forward, last year I could made my full switch since gaming on Linux became a thing but definitely was not plug and play.
