  • Not all distros ship SELinux and the ones that do, don't actually configure it securely.

  • New users are expected to keep copying and pasting commands from their browsers to their terminal which compromises some Linux security defenses.

  • KDE, GNOME and Sway are the only functional Desktop Environments/Window Managers that support Wayland all, while the Other DEs are not even close to shipping with Wayland.

  • Most if not all of the Linux Distros in 2025 ship with Grub bootloader, which suffers from a lot of problems, instead of using the bootloaders that does not support BIOS and will improve the reliability of booting and provide a more stable experience.

I will agree with you that Desktop Linux leaves a lot to be desired from a security perspective. But, I'm not sure if these are its biggest problems.

Not all distros ship SELinux and the ones that do, don’t actually configure it securely.

Is SELinux employed on Desktop Linux the very same way we find on Android? Unfortunately, no. So, there's definitely a ton of mileage to be had here. But, there's literally nothing that stops you from making a fortress out of it. So, the ones that are intimately familiar with SELinux will leverage it to perfectly suit their needs. Which, is the only truly sensible way one should use SELinux to lock their system. Being dictated by the defaults set by the distro is only a counterproductive exercise of comparing/contrasting threat models.

New users are expected to keep copying and pasting commands from their browsers to their terminal which compromises some Linux security defenses.

They're absolutely not expected to do so. What makes you even think that's the case?

KDE, GNOME and Sway are the only functional Desktop Environments/Window Managers that support Wayland all, while the Other DEs are not even close to shipping with Wayland.

This is your best point. I agree that other DEs should haste in supporting Wayland. Though, at least I find solace in GNOME and KDE Plasma being the most used DEs/WMs to begin with. Hence, even if only those two would support Wayland, we would still have allowed over half of Linux' users to choose Wayland.

Most if not all of the Linux Distros in 2025 ship with Grub bootloader, which suffers from a lot of problems, instead of using the bootloaders that does not support BIOS and will improve the reliability of booting and provide a more stable experience.

Sorry, I'm not familiar with this problem/issue. Would you please be so kind to explain why I (or anyone else, for that matter) should worry about this? Like, what "problems" are we talking about? How is (allegedly) GRUB not reliable or stable compared to the others?

Btw, just curious, what are your thoughts on secureblue?
