@oceane @lrvick oh, we are very much working with and for people in heavily repressive situations and they often use #deltachat when signal, threema, WhatsApp don't work .... And even if they do. Why? Because our apps provide instant onboarding without phone numbers, multi-profile and multi-device support and a pretty secure audited and analysed key management protocol without key servers. Plus support for state of the art circumvention proxying. There is a whole lot more than PFS to consider.
