I mean, go off about it not competing, that's some BS. But Linux doesn't offer the compatibility and ease of use that Windows has on a day to day basis. There's not really any argument to be made there.
Frustrating antipatterns, poor design decisions, poorly communicated reasons for functionality loss with updates (what this article is about), and settings requiring hoop jumping to touch aren't unique to Windows and magically never present with Linux.
Linux is amazing, neccessary, and I sincerely hope it continues to grow as a valid competitor eventually taking over, but it's still really rough in a lot of areas as a power user.
There are a handful of very user friendly distros for people who just need to do basic stuff on their computer and have it just work. Web browsing, document editing, even playing games that are just semi-popular (instead of only the most popular) all tend to work to a reasonable degree of "it just works" now.
There's also an amazing amount of customizability and power placed in the hands of the user if they're willing to dig into the guts of it. Run your own customized kernel with the specific patches you want, re-code part of a driver to meet your needs. Build an entire distro from source code up, piece by piece, exactly to your wishes. Compatability layers between different desktop environments. Mess with your drivers. It's all open to mess with.
But what often gets left behind are people in the middle. I need a lot more than just basic functionality, and I have no fear about compiling stuff from code or making pull requests. I have the skills to make Linux work. What I don't have is the time in my life to be digging in the guts regularly to get shit working on my computer, which is still far too often a requirement with Linux. Just look at discussions in the Linux communities here to see how absurd it can be to get a RDP or VNC client working, depending on your particular setup and graphics card.
It's like the difference between getting a Honda Civic and working on a project car. You might need to change a tire, brake pads, change the oil on the Civic. You don't need to mess with engine valve timings.
I really enjoy tinkering with Linux when I have the time, but most of my life I need my shit to just reliably work so I can get my shit done. I prefer my computer to be a tool far more than a project, and Linux is still too much of a project for a lot of people.
