A mass exodus from Whatsapp created a great opportunity to change a whole landscape of communication tools, but seems it is already missed though. Instead of switching to wonderful self-hosted (rocket.chat, element) or even p2p serverless (briar etc) alternatives, millions of ex Whatsapp users stuck with yet another centralized USA-based messenger - Signal. Sad.
btw Crypto AG story increases chances that some services and companies even marketed as super secure and NON-US could be secretly owned by us government :) https://www.forbes.com/sites/daveywinder/2020/02/12/cia-secretly-bought-global-encryption-provider-built-backdoors-spied-on-100-foreign-governments/
