Power users are the exact people who would get the most benefit out of Linux, though. Speaking as one of them who got sick and tired of Windows' bullshit. I'd argue Linux already very much competes with Windows, and has many advantages sourced from it being an open and not profit driven operating system.
Finally do I have an operating system that actually tries to work with me to get what I want, rather than tries to obstruct me every part of the way because "it knows best" or whatever windows tries to do.
