1/ In defense of #Signal. Yes, I'm a guy that just posted a roundup of distributed/mesh messengers https://changelog.complete.org/archives/10205-roundup-of-secure-messengers-with-off-the-grid-capabilities-distributed-mesh-messengers of which #Signal was obviously not part. I am really excited about the potential of those.
But to the general public, I still recommend Signal. Here's why.
For some colleagues whith whom I shared the ridento work, I simply rold them I'd rather use Signal than SMS or Whatsapp -- I don't have Whatsapp, and Signal is free and pretty much the same to use, except it's not owned by Facebook. That worked for most -- though some deleted Signal again when we were no longer driving together.
I only brought up privacy when I had some time and thought they were willing to listen a bit.
I found it harder to go the other way round.
Another thing that can help:
"Here's my email, Threema ID, phone number/Signal ID -- pick one!
Also have an XMPP adress and Briar, butbtheycre a bit hard to use."
if the other person only has Whatsapp, it becomes harder for them to say no to installing a second messenger, and also harder to think the reason you're not on Whatsapp is that you're some hilbilly/conspiracy theorist who's scared of technology, but actually know your way around messengers and such.
