I come from point of ignorance and agree with you.

I do not understand what privacy security or anonymity I can have, when we start with sharing my most identifiable personal information with the app and all my desired contacts. (whatsapp takes it further by refusing to work without full access to your contacts which... Just, no).

I feel I'm in a twilight zone as everybody cheerful regresses to apps you have to bootstrap with your phone number and then proceed to basically only work well with your phone - teeny tiny screen with awful keyboard, instead of allowing me seamless access across my communication devices and preferences.

Messaging seemed like a solved problem until we made it inexplicably and massively worse.
