It has been a long journey.
I have been gradually convincing my family, close relatives and friends to make the switch to Signal for over two years. I am already the “tech support guy” in all my circles so most didn’t really question it. Most of my friends are quite tech-savvy, and some even did use Signal before I talked to them about it.
This also filtered out some “friends” who were never that close to me to begin with. So, that’s a bonus, I guess.
Overall, my recommendation to others interested would be to tell people how much you don’t like Meta’s business model instead of the privacy aspect. I already ditched Facebook and Instagram many years ago, and this helped defend my point a bit better.
It’s not really that they get the clear texts, but that they get access to who you talk to, when, and kinda how long are your messages. That metadata is super valuable. Over long periods, just with that metadata there’s a lot that can be inferred.
