It’s not because it’s not used by the common public, it’s because there aren’t normie-friendly resources and or a company help desk that average people rely on when they need assistance. It’s all well and good for people to say these things are easy to learn and they don’t break, it in the real world, for people who don’t really care about this stuff but have to use it for a few random tasks, it’s nice to know there’s a place that will help you. Not everyone has a techie friend or relative.

The issue is not with the software itself (although there are issues there) as much as it is with non-commercial nature of Linux. It’s great that there’s a thriving community of people who are passionate about this stuff and get great use and enjoyment out of it, but many of the reasons people love it are also reasons why it will probably never be a viable mainstream option.
