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.
I’m thinking about abandoning Signal given the fact that they use AWS servers, still insist on requiring a phone number to use the APP and haven’t yet implemented nicknames like Telegram
If you want absolute control over your communications, the only way is to self-host an XMPP server
Your data is always encrypted before it reaches the AWS servers though, so it’s not like Amazon has access to them. The phone number/nicknames is still in progress, but it’s hard to do that securely, and given that their user base is really big now, they also need to make sure it works well for everybody.
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.)
Matrix, the protocol, is quite nice.
Element, the Matrix reference client, is too complicated IMO. If everyone were to only use FluffyChat, it would be great but then FluffyChat afaik doesn’t implement every protocol feature and and you could end up in compatibility issues with Element users.
Purely as a client I find Telegram the most convenient. I think more should copy their homework from there, heck perhaps post the client to Matrix.
