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.
Agree that in practice SMS are intercepted just as much as Emails. But its entirely different and SMS does not use RSA afaik.
The last paragraph stressed for me how confusing this would be for noobs. A messenger that seems to do exactly the same but differently. People would not get it and think if they use Signal for SMS this would be secure somehow.
Whatsapp never integrated SMS and its used everywhere. Okay, there are video conference platforms that allow to log in via the phone network, but yeah, dont do that.
