I helped setting up Conversations / Monal on my grandparents phones and they have no issues sending messages.

My grandmother lives 700 km from my home, I can't be there every time she changes her phone or breaks something.

I can instruct a non-technical relative to install Signal. Installing Conversations and configuring the right account on the right server is another story.

Maybe https://quicksy.im/ would work in that case. Easy to install like Signal, but it uses your phone number as a routable XMPP address. Unsophisticated users get easy onboarding and nobody else gets locked into some walled garden.

This isn't good enough.

Quicksy "advises you" to use OMEMO. It doesn't make OMEMO always-on.

It's encrypted by default. I agree that having no option to send unencrypted messages would increase security somewhat, but the unsophisticated user can always be tricked into sending an unencrypted message. They will just use a different app if something doesn't work. Not really fixable on the application level.

Try sending me plaintext with Signal.

That's the fucking bar you need to meet.
