Earlier quoted context omitted.
Quitting Facebook itself would help with what you are saying, but I am curious what you replaced WhatsApp/Messenger with. For example, I have good friends in other countries, and sending pictures and short texts is one of the best ways to stay in contact. We do talk over the phone occasionally, but not having a simple way to send pictures or links would pull us much further apart. Sure, email could be an option, but…
Telegram might be convenient, it's a middle ground between bloated Facebook things and "geeky" apps like Signal (I don't dislike it, but it's just unpopular).
Also i dont agree at all that its more geeky. If you don't think about technical backround Signal is ux wise simpler app.
