I suggest adding signal and telegram in your next poll. My grandma can use Signal. I avoid Telegram but it is popular nonetheless.
@basvanhaastregt Sorry I only read your full post after voting and responding. Signal hosting on AWS is a vulnerability. Although backdoors are absent, Amazon could shut down the servers like they did Parler. I expect that to be unlikely because of the backlash and that Moxie has a contingency plan. It is just the easiest service for the less competent people to use and adopt. We all can relate with the difficulty of getting some people to encrypt. XMPP and Matrix are my preferred.
@krock
I left Signal out because it's, as far as I know, based in the US.
I don't want to use services that are based in the US, because there are questionable rules there.
