You may feel that way, but not every power user is like you. Linux distro is not a monolith, it’s made up of thousands of small components made by different people and organizations. If you look at some of those components source control (e.g. on GitHub or GitLab), you’ll see a large portion of pull requests are done by their users who found bugs and decided to submit a fix themselves. For example, just look at how many pull requests libgweather got, and they’re mostly submitted by gnome users who were mildly annoyed with the weather app.
