Im very impressed with Slidge whatsapp bridge on my Prosody server. It is far more stable and reliable than I ever expected, and means I do not need any Facebook owned apps on my personal phone, as whatsapp is installed on my work phone only and slidge is linked to that ( my workplace use it, because free and “everyone has it” heh.)
My family have refused to move over to xmpp after the matrix server we used shut down, even after I ran a few different test servers on both prosody and ejabberd and tested reliability of the platforms and mobile notifications. (Both work great, but at the time I decided on Prosody.) My family’s reasoning was that they already use whatsapp and I’m just being weird.
The slow creep of rights and privacy erosion is disturbing to me, and the small amount I can do like running my own fedi instance and chat server at least helps me keep my sense of sanity in this crazier and crazier world of surveillance and data harvesting.
A bridge to the chat platform at least means it isn’t on my phone that is with me everywhere, and doesn’t inconvenience my family from me being the “weird extremist”.
We do what we can.
