This essentially all boils down to “I don’t like new things, and despite it being made more secure, I don’t trust it”
No, quite the opposite, I like new things, just in my own direction. Which would be simplification. We’ve had this exponential growth of computing power and complexity and expectations in the last 30 years, which can’t go on.
Again, where you’d use a screwdriver 100 years ago, you’ll still generally use a screwdriver, possibly one as simple as 200 years ago, but with computers we for some reason have to hammer nails with a microscope today.
A personal computer should be as complex as Amiga 500 tops.
Wasting 1000 times the energy to try and make it easier to use than that still hasn’t yielded satisfactory results, for a sane person this means stop.
The rest is just gaslighting.
How are sandboxes “untrusted crap”?
What you run in them is untrusted crap.
yet you seem to prefer X11 over Wayland, and 500 different implementations of the same thing, implemented separately by every app developer,
Yes, what’s standard in X11 has N different variants with Wayland. Correct.
rather than using a standardised xdg-portal
I don’t use it at all.
If you meant that Wayland is simpler than X11, let’s compare them when Wayland reaches feature parity. Also X11 as a standard is simple enough.
I also consider Nix and Guix to be better solutions to some of the problems Flatpak and Snap solve, and Flatpak and Snap to fall short of solving others.
