I'm from the NLs and removed WA last year. What I liked about switching to Signal: people who care about me also installed Signal, so I didn't lose that. What I did lose? All the groups that I got into through the years, all of which were completely non-essential. If I need messaging with someone outside Signal I just use sms. The best part of leaving WA is that you'll find a lot of people willing to install Signal for your sake, and that's how it becomes easier for others to make the move.
