Ah, the classic "CLI commands are universal" nonsense. Isn't even true with poweruser distros (look at Alpine or Nix), but neither with common ones. But I'm sure reinstalling grub on a systemd-boot distro can't be that bad, right? Here, quickly install something to fix that. Oh, your distro doesn't apt but pacman/dnf/zypper/whatever? Too bad, don't know those. Wait, why is that config file missing? Oh, your distro saves it somewhere else, sure hope you didn't copy some script from the internet that now failed halfway through!
Surely after copy-pasting all those commands the other person has learned something to help themselves next time, other than that they're utterly lost on Linux without the help of others. This will definitely make people use Linux instead of going back to the exploitative OS they know where they at least feel comfortable enough to know it won't fail on them.
You guys seem so utterly disconnected from the common user's perspective it's not even funny anymore. Expecting everyone to learn all those CLI tools and system components they may encounter… I hope you guys are also mechatronics engineers if you drive cars, botanists if you have a garden and at least intermediate chefs if you own more than the most basic kitchen.
Please go out and talk with some people who're NOT into tech about this stuff, it's a sobering experience.
