Looking for a mom-and-pops-friendly IM solution
tl;dr: I'm looking for an alternative to #Whatsapp that is easy enough for my nontechie family to use. So far, #Matrix looks like the most complete solution, but seems pretty slow these days for some reason. Also, I have reasons on why I'm not 100% on choosing #XMPP this time.
What is the alternative you would recommend to mom and dad?
#CambridgeAnalytica leaks and #Facebook scandals apart, I've already been looking for an alternative to WhatsApp for many years, with the largest hurdle in this crusade definitely being the fact that my family hasn't been keen on leaving it for another app. On my side, I have the following requirements:
End-to-end #Encryption enabled by default, or at least built into the program (native implementation, no third party plugins)
Clients exist for at least GNU/Linux and Android platforms (more is better, but not needed)
Support for group chats with E2EE
Supports at least text and image transferring.
