Linux

Possibly. But it's also pretty common in many instances of technology adoption that as more users come, the quality gets worse, and while open source doesn't have to worry about a shareholder-driven profit motive driving it, it's still easy to wind up with a muddled focus. I wouldn't expect that Linux and all of the associated software projects that make the functional desktop are going to be an exception overall. If you're an open source developer working on a project now, basically any user is some form of power user, and it's easier to find consensus of what to prioritize on a project not only because Linux users tend to be better about understanding how their software works and are actually helpful in further development, they're also likely to direct development towards features that make software more open, compatible, and useful.

Now fast forward to a future where Linux is the majority desktop OS, those power users are maybe 5% of the software's user base, and every major project's forum is inundated with thousands of users screaming about how hard the software is to use and, when bug reports and feature requests are actually coherent, they mostly boil down to demands for simpler, easier to understand UIs. I can easily imagine the noise alone could lead to an exodus of frustrated developers.

Some things are better for NOT trying to be the answer for everyone.
