I’d love to switch back to Linux but this is why I moved back to macOS for good several years ago. Once I got a taste of reading code at 4k/retina (faux-4k) – not to mention the better font support – there was no going back, for me at least.
If it’s considered user error for someone to want a high DPI display in 2024, then I can only surmise that people who share that sentiment have convinced themselves that more eye strain is a worthwhile tradeoff for FOSS. Commendable but a tough sell.
I run Linux with 4k on my Ubuntu box and it's no problem, except for Java apps. I don't think it's Ububtu specific. In the Settings of Gnome you have the choice to scale everything, if needed. I prefer to scale individual things, so I get more space.
