I have to question that.
Nearly all of my worst experiences when using Linux have involved software that they or their developers have, to the best of my knowledge, been significantly involved with creating.
I'm thinking of software like systemd, PulseAudio, NetworkManager, GNOME 3, and Wayland, for example.
I've wasted far too much of my time dealing with unnecessary, silly, and inexcusable problems involving such software.
What makes it even worse is that despite me trying to avoid their ecosystem, their software has unfortunately still made it into other major distros, including Debian.
