There are big wishes for Signal to adopt the perfectly working Flatpak.
This will make Signal show up in the verified subsection of Flathub, it will improve trust, allow a central place for bug reports and support and ease maintenance.
Flatpak works on pretty much all Distros, including the ones covered by their current “Linux = Ubuntu” .deb repo.
To make a good decision, we need to have some statistics about who uses which package.
Signal also encrypts your metadata. (And notably, WhatsApp does not.)
That seems like the wrong place to link to. Shouldn’t you be linking to Sealed Sender?
