it’ll take years for achieving even the current level of usability that Windows provides out of the box

I’m currently dual booting Windows 11 and Ubuntu 22.04 and would say that gap has already closed. I cannot really work with the shell in Windows because it does not seem to understand bash which makes things difficult. The windows package manager is very cumbersome to use. Customizing the DE is a hassle and I cannot switch to other DEs. Most of the code base is closed so I cannot really see what is getting executed in the background. The settings come with telemetry enabled on default. I think it does not even have Vim installed.
