I am really confused why not more people consider switching to the Conversations XMPP client (or the blabber.im fork).
It has all the features comparable to WhatsAPP/Telegram/Signal/Matrix etc. but is fully libre, e2ee, decentralized and by far the most privacy preserving. And you can easily use a XMPP Desktop client like Gajim or Dino with the same account.
And there are tens of thousands local and non-profit XMPP servers to use and self-hosting a XMPP server for your and your friends & family can be easily done on a RasberryPI from home or really cheap VPS (contrary to Matrix).
There is really no comparable alternative out there, so it is really baffling that it gets recommended so rarely.
I used XMPP before knowing signal, and this IS so difficult to make people migrate to signal that it will be impossible on xmpp
