Ask HN: A Minimalist Messaging Platform

Seeking thoughts on idea of Minimalist Messaging, looking at current state of affairs especially referring to existing dominant players, none has actually hit the right balance of Privacy & Usability, we are thinking to build a platform which is minimalist , no feature bloat, Zero data selling and surveillance, no phone numbers required. Our focus is primarily on Privacy and Usability. Appreciate feedback , you can be as critical as you can, don't hesitate, thanks.
