I don't hate computer games or young people, I've had both for ages.

I'm not a big fan of Valve, or the billionaire running the app store from his mega yachts.

I'm sorry, but that's not how you come across, at least to me. I can understand not liking Gabe and I can even understand not liking Valve, but your complaints about their incluence on the Linux ecosystem seem entirely unwarranted.

BTW'ing seems relevant. It's an ecosystem that's been largely focused on turning a gnu/linux workstation into an x86_64 Steam player for over a decade and now Valve are using BTW as $UPSTREAM. It's what this kinda thing evolved into as actually compiling stuff was harder than copy and pasting ''yaourt eyebleach-kitchen-sink-bin steam" https://www.shlomifish.org/humour/by-others/funroll-loops/Gentoo-is-Rice.html

I'm sure speaking in riddles doesn't help, but I think I understand what you're saying. Valves decision to use Arch as an upstream distro makes complete sense to me. They would want pick and choose from reasonably up-to-date packages, roll their own kernel and make use of some of the community effort to facilitate gaming on Linux.

Ask a question on X11 in the world of BSD, Debian, RHEL, Ubuntu, Raspberry Pi OS, Gentoo, Alpine, Rocky, MX or in the nerd mines of Phoronix, Linux Questions or Stack Exchange and people will help that have knowledge, ask in BTW lands and there will be witch hunt by people who have no idea what they are talking about.

The wave of popularity for Arch got memed into existence a while ago. Long before wayland was even a viable alternative. Of course the communities suffered some collateral damage in the form of noobs, but that's not a new thing either. Most mainstream distros have had these kinds of issues for a long time. You're not going to be able to blame Valve for that. Phoronix is a poor example imho, that site has always been full of idiots and not moderating the forums has opened the gates for all kinds of lunatics. Ever read the forums under a piece of news about Rust? It's a lot of very opionionated idiots who know extremely little about programming. What about the arch forums? They've been reasonably helpful and knowledgeable for the longest time, yet they are part of "BTWland", no?

If X11 goes down it would be like Mad Max: International banking and airports screens would just go black, Moscow, Pyongyang and Beijing too..even more important stuff like adverts could stop working at scale.

I'm not impressed by the technology choices of businesses and public infrastructure. Most of it uses Windows anyway for some godforsaken reason. I know you're being dramatic, but even if X was just yanked out of existence, for the purposes of digital signage or other such extremely basic computing tasks it really shouldn't be such an issue to switch to something else. Most issues would probably crop up on Linux workstations, running a bunch of software through XWayland. The vast majority of Linux computers however, don't need a display server.
