flatpak works by using bubblewrap which creates namespaces for the applications you use, essentially the root gets swapped for a fake root, this is how docker, podman, etc work.

This contradicts their own wiki. Type 2 AppImages do use libfuse2, which is the problem

appimagekit is not actively developed anymore. Development moved to AppImage/appimagetool and type2-runtime

EDIT: Also go-appimage which was the first one to use the static runtime in 2022.

So no, they do not need libfuse2 anymore. Stop saying that nonsense, Download the AppImage of Cemu or PCSX2 or Ryujinx and remove libfuse2 and see for yourself...

Even in the github thread you linked it is said that namespaces are enabled by default in the kernel nowadays

Yeah and ubuntu recently fucked it up with namespaces restrictions.

Docker, where another kernel, package manager etc. gets loaded.

Docker doesn't load another kernel, no idea if it can either, flatpak is pretty much another package manager as well. By your own definition it is another distro.

However if you want to be taken serious in your criticism please inform yourself on what you’re criticize

they simply don’t fix the libfuse2 issue

Neither Flatpak nor Snap run “another distro inside”

The flatpak runtimes are huge and are another distro in practice, just check the contents of the gnome runtime and you will see it is another distro.

Flatpak also depends on namespaces which paranoid distros disable and cause issues. Which the person you responded to talked about it and you ignored all together lol
