It’s not an ecosystem of one, though one is very dominant.
You can compare it to Linux. It’s not the only Unix-like kernel, but it’s similarly dominant. If you want to create a new distribution, it doesn’t make any sense to spend a decade trying to write your own kernel rather than just using the Linux kernel (insert GNU Hurd jokes here).
Is that an unhealthy ecosystem then? I don’t think it is.
What makes the chromium situation unhealthy is Google’s ownership and control, not that it’s the preferred engine for other browsers. I mean, even a company as large as Microsoft gave up trying to create their own engine.



I mean, that’s basically how I find the root cause of problems that occur in one environment but not the other.
Most recently was when a plasma desktop of any newly created user wouldn’t shut down properly, at logout it would hang for about a minute with an error in the logs stating that
plasma-plasmashell.servicewas not responding to a sigterm, and was then ultimately force killed by systemd. On my main desktop, I didn’t have this issue.By meticulously diffing plasma related config files, I found that the culprit was in
~/.config/plasma-org.kde.plasma.desktop-appletsrc. Disabling a few system tray applets that I didn’t need (and that I indeed had already disabled on my main desktop) fixed the issue.
