I am trying to convince my group to switch from WhatsApp to Signal and we plan to vote on it soon. So, I plan to use the replies in this thread to compile a list of reasons to use as talking points. Preferably, I need something that can be understood on a personal level as some of my friends are deeply cynical and have no concern about escaping techno-feudalism and surveillance.


This is a good response.
I’ll add from an argument perspective, try to make Signal sound as similar to WhatsApp as you can, then highlight how it’s better.
Don’t bash WhatsApp, it’s an entrenched default (first man in advantage). At worst, highlight why you don’t support it. Humans love homeostasis, even if it’s not good for us (the devil you know) - ppl may actually like it and you have to convince them why your option is better.
Happy persuading!
