I understand that it may be problematic sometimes but this was very smooth. I didn’t even say anything.
A: what’s your number for the whatsapp group Me: I don’t have whatsapp because of facebook. B: ok, we have to use signal then A: ok
And that was it. Life can be very easy sometimes
I’m pretty sure an encrypted chat platform is possible with ActivityPub.
Why reinvent the wheel, tweak a protocol, implement a ton of software when you can just use the tested, tried and true XMPP?
