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.
The concerns about AWS servers are around metadata. If metadata were not a concern, why not just use Whatsapp? They use the Signal protocol so messages are end-to-end encrypted by default, and most people already have it or are willing to download it as compared to Signal.
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?
Yeah that might be better! I knew of my link off the top of my head, which enumerates what unencrypted data Signal does have access to, i.e. almost nothing.
