Flatpak permissions for Cryptomator, and wayland support

The flatpak version distributed in Flathub needs permissions:

  • Network, share=network (to access network)

  • X11 windowing system

  • Several Talks: several Org.freedesktop, and org.gtk.vfs*

Why does Cryptomator require access to the Internet or network?

The X11 windowing system is known to be very insecure. Is their support for Wayland?

Can we reduce the number of talks, like vfs*?

Also, the appimage version requires access to the various /tmp directories (and system files), but the flatpack version does not need this access. Why?
