Today, it is practically impossible to survive being a significant Linux maintainer or cross-subsystem contributor if you’re not employed to do it by a corporation. An interviewer to the Linux dev that's mentioned in the article: "So what did you do next to try to convince the Linux kernel devs of the need for more focus on end-users?"
I appears as if Linux is a nest that is not built with a consistent set of user-centric principles. Instead, it seems that each part of the nest is built with a specific corporation or project in mind.
Assuming I'm right that Linux is built with project-based thinking and not product-based thinking, I do wonder what a user-centric Linux or another user-centric FLOSS OS would be like, an OS that is so smoothly built that users come to think of it not as an OS for tech-savvy people, but an obvious alternative that you install immediately after getting a computer.
If Linux is indeed built with project-based thinking, then I wonder why that is. The uncharitable explanation is that someone doesn't want Linux to have a MacOS-like smooth and gorgeous experience. If you don't think MacOS is smooth and gorgeous, I'll address that.
I know some people have suffered immensely with Apple products not only because Apple builds devices that can't be repaired, but because of things simply not working. However, there are many people who love Apple. That's the kind of passionate advocacy that I would love to see in Linux, and not just around freedom and value-based judgements. I want Linux to be thought of as the least-friction tool for professional or recreational use. I want people to think of Linux as gorgeous and usable.
Of course, we can apply Hanlon's razor to this situation ("Never attribute to malice that which is adequately explained by [ignorance or lack of skill or practice]."). Managing a product is difficult. Managing a community is difficult. When the nest's design is not built by a team constantly seeking to care about users, but instead by a bunch of users pecking into the nest until their corner is shaped the way they want, it's not surprising to see a lack of user-centricity.
