Don’t recommend Voyager as a desktop client to new users. It just looks like a stretched mobile app, and the UX on desktop is piss poor. Just go with the default Lemmy UI, or Photon.

Reasonable choice

Bad choice, many new users specifically came here because of !piracy@lemmy.dbzer0.com, which can’t be accessed from lemmy.world.

It’s still commercial, proprietary software

That’s not true. Moxie only had a problem with a fork called “LibreSignal” because it was using their name. He didn’t want users to confuse the apps.

There’s nothing inherently wrong with Sup, but it’s very new and hasn’t had the chance to stand the test of time yet. It also has very few users and isn’t as intuitive as straightforward as Signal, which is basically just a carbon copy of WhatsApp (UI/UX-wise). Network effect is a very important aspect.
Federated networks aren’t easy to explain to users, this is already a huge issue for Mastodon, and it’s probably why it hasn’t taken over social media.
As other comments here have pointed out, Sup would be a closer alternative to stuff like Facebook Messenger than to WhatsApp. I’d say Signal is still the best option for private and secure instant messaging.

Sup Signal = WhatsApp

Not really, but Instagram and WhatsApp are still massive
