So, Linux is written by system programmers for system programmers.
This must be one of the most uninformed comment in a long time. Already 2001, there was quite a lot of UI work being done by the company Eazel, founded by Andy Hertzfeld who from Apple and with a bunch of former Apple people. Around the same time, Ximian (I think) was pushing project Utopia with the idea to form project teams of people from kernel devs up to UX, to ensure common tasks worked out of the box. One result of this is that printer configuration on Linux is a much easier than on any other OS. This all happened 20+ years ago, there have been quite a lot of UX people involved after that. And my experience is that people with little prior knowledge have an easier time with a modern Gnome desktop, than with Windows. The problem here is that most people know Windows to some extent, and are used to the weird quirks there, but any slight inconvenience on a new OS make them quit.
Saudi Arabia felt Twitter was a problem, so they paid Elon to take it down in a way it wouldn't come back.
