I’ve seen many threads suggesting products but they often don’t mention FOSS projects, which should always be preferred to corporate software. With FOSS you are already boycotting capitalism, on either side. Free and Open Source ignores borders and shouldn’t be categorized in nationalist terms, no matter where some of the maintainers happen to live.
I moved my whole family since years to Delta Chat, eventually started contributing to the project and even created my own fork that is what my family is using, see: https://lemmy.ml/post/26007254
i huge recommend both SIP + XMPP software :)
ArcaneChat is dope. I’m testing it out with my partner right now. The built-in Jitsi button is super helpful. My extended family (about 30 people) switched over to signal a few years ago, so there is some inertia there, but for any new chats, DeltaChat (and ArcaneChat for Android users) is what I’m going to push for.
