A family member is moving out of country and convinced the best way to keep in touch is with WhatsApp. I really don't want to install any Meta shit on my phone.
Any recommendation for a FOSS or other alternative from a company that's less of an ethical dumpster fire?
As is the highest up vote, Signal. However, if you refuse to install WA (you should) and they refuse to install Signal (scold them for being dumb), a backup is to bridge WhatsApp with Matrix and use Element on your phone. Way more complicated than Signal and I still strongly recommend they use Signal.
Yeah but IMHO bridging whatsapp misses the point. We need people to start being aware and choosing conscious ethical pieces of software for the sake of humanity.
Works great for me. Only oddity is "quotes" in Discord sometimes dont show the content unless you tap on them. And yes, look at the bridges page for more. https://www.beeper.com/ is a hosted version of this with a custom app.
