"Linux" is a de facto term I've come to use. For the first N years of using Linux, I was a good little Stallmanite, went around running vrms, felt bad about any proprietary software (and met a good friend with the opening line "quick, I must find a computer running only Free Software!" - true story), etc. I would also go around correcting people about using the word "Linux" when they obviously were just uninformed and meant "GNU/Linux", and it isn't "hacker", it's "cracker", etc. etc. etc.
But now I don't care. 17 years later, I'm 30 and the entire world calls it "Linux". I know what it *really* is. I've read most of the kernel source out of sheer random bedtime reading. I used to do an LKML podcast just because I was that keen on reading LKML. So I think I get enough geek cred that you can accept that I know what "Linux" is, and I'm choosing to go with the term that the *entire* rest of the world is using at this point.
As to the rest of your comment. You make a good point. Many people would not want to use the only possible platform that is going to make "the Linux desktop" successful for a mass audience. The only way to do it is to have locked down APIs, far less churn, less re-invention, and a stable base that applications can target for many years at a time. See also Windows, OSX, Android (API revisions thereof), and so on. Enterprise Linux is successful because it fixes this mess in the server case and creates a stable base for folks to target. But doing that on the desktop is extremely unlikely to happen for all the reasons that you cited.
Note, I'm not that personally devastated. I use Linux as a server and embedded OS. I use it as a desktop for working on stuff (where I get to enjoy just how nearly close Spotify runs under Wine these days) but for media consumption and weekend hobbyist projects? I use a Mac for my desktop because I have X amount of time and I don't want to spend it fixing libraries, upgrading the rest of the system (python, every core library, etc.) just to install one application, and so on. I've made my peace with reality. I'm just trying to point out that if for some reason anyone still cares about getting to the "year of the Linux desktop", it will never happen until the issues in that article are fixed. Desktop users (the kind we'd actually win) don't care about shiny, they care that Microsoft Office from 3 years ago "just works". That's what would be required if we actually wanted to have a mass userbase on the desktop.
