Mainstream messaging apps are privacy scams. WhatsApp and iMessage use closed code, making it impossible to verify their encryption claims. WhatsApp has already handed over conversations to authorities while selling the idea of security. All rely on centralized servers, a single point of failure and censorship. They collect massive metadata: your IP, who you talk to, when you talk, your complete social graph. The requirement for a phone number is absurd for anyone seeking real privacy, opening the door to SIM swapping and deanonymization. They're vulnerable to MITM attacks when central infrastructure is compromised, remember those American agents who fell for Russian phishing via Signal? XMPP with its federation allows interconnected independent servers and native GnuPG support, but SimpleX goes further: it eliminates permanent identifiers with its unidirectional channels, protecting even against metadata analysis that XMPP allows. No number, no email, no identifier whatsoever. True privacy requires control of infrastructure, not trusting companies that profit from your data Not your keys, not your data
