How have others gotten friends/family to make the switch? I’ve been doing a cleanup of my digital life over the last year or so and am trying to move to using more privacy friendly alternatives where possible.
example: I’d love to switch to Signal only but everyone I know only uses WhatsApp. I’ve mentioned switching to people in the past but it’s always the same response (I don’t have anything to hide)
Yes, the XSF has a very high bar what a standard is and what not, so the many protocol extensions are labeled experimental. However that doesn't mean implementations are "incomplete" or "insecure". OMEMO has good support nowadays and the implementation in Conversations has been independently audited.
Sorry but I've been burned by WhatsApp before. Not wasting time on moving my contacts to another walled garden again. XMPP is actively developed and has most privacy features Signal does + most providers don't require a phone number and let you connect over Tor. Doing things properly and in an interoperable way takes more time but is absolutely worth it: https://snikket.org/blog/products-vs-protocols/
Interoperability and standardization is not just a virtue, it is a necessary condition for sustainability. Unlike Signal, modern XMPP implementations have great privacy properties AND great sustainability properties.
Matrix is a much better choice than Signal since it offers provider choice, but I wouldn't be sure it's any better than XMPP in terms of usability or sustainability:
