I quit WhatsApp, Facebook et al and went with Signal. Initially it was hard converting people to a privacy oriented service, but today I have an endless list of open chats in Signal.
It was also pretty easy to get my family using Signal because it uses your existing address book. The need to send a Jami address is a huge hurdle for the non-technical.
We have to switch to decentralized open source solutions. I have tested Jami and the video conferencing functionality works great on Android.
