This is like saying Red Dead Redemption is like running a farm in Texas. Linux is more popular among techies/programmers/hackers. Cyberpunk is a genre focusing on being cool and special, an attempt to steal computers from introverts and hide the boring stuff they find exciting. It's a computer Wild West.
I disagree with your overly strict definition of cyberpunk :)
I'd rather say that Cyberpunk has a focus on what is cool, rather than on "being" cool, with the disitnction that the former definition exploits the inherent coolness of all things cyber, where the latter is much more superficial.
Look at the people and works that founded the genre, they looked at REAL stuff and extrapolated, not because the real stuff was boring, but because it was cool as hell and the future stuff would be even cooler as heller. ;-)
Success in such a setting is not determined entirely by the luminosity of ones hair, the gnarliness of ones implants, but also the deep technical understanding of all the boring stuff, it's so deep, and so understood that one can do it swiftly and make it look both easy and cool. What we get to "see" in cyberpunk novels, movies and games, is mostly an abstraction sice we're not that cool dude or dudette, we don't have that deep deep understanding or those amazing skills, maybe we just lack the right implants, but nevertheless, the author is forced to portray some hybrid between the "concept of what's going on" and what observers would see.
Also, Duskers is a great game.
Ps I'm a Linux user and I'd love to see more native games for my platform of choice, but I also know that there's a reason I can't always have nice things, and I don't blame anyone for that.
I think the worst that has happened to Linux games was that DirectX has won. Vulkan gives me some hope.
Cyberpunk is superficially about technology, but I think Noita is a much geekier game. Made in Finland, the country that added demoscene to Unesco. Every pixel is simulated, lots of tinkering, emergence; you craft your 'weapons' all the time. The game's requirements say: "The more cores the better".
Note it's common among reviewers to say Cyberpunk is NOT about technology but rather about capitalism in overdrive. The game's technical themes are all old cliches: Johnny Mnemonic, brain machine interface, computer viruses.
