People say more Linux availability would make it mainstream. However, Chromebooks are one of the most available laptops. The software is 100% compatible with hardware, and in many cases, the Play Store is included to address the lack of software. That is more than enough for casual computing and office work—two massive segments of the PC user market. And people still don't like them. ChromeOS's market share is similar to that of all the other Linux distributions.

I think the Windows and MacOS brands have become lifestyle choices. Windows is the "gamer" and "corporate" choice. MacOS is the "student" and "luxury" choice. Linux is the "hacker" choice (they use Arch, by the way). Like iOS vs Android, Xbox vs PlayStation, Toyota vs BMW, and all other brand tribalisms, it seems like most people are emotionally drawn to one or another.
