Apple & Google Activate End-to-End Encrypted RCS Between iOS 26.5 and Android

Like BlackBerry’s 2005 move to encrypt BBM traffic or WhatsApp’s 2016 switch to Signal-protocol E2EE, this rollout marks a tipping point where mass-market, default texting finally matches the privacy bar long set by over-the-top apps. It reflects two intersecting mega-trends: (1) regulators forcing Big Tech toward open standards (EU DMA parallels the 1982 AT&T breakup that compelled interoperability in telephony) and (2) a decades-long march toward ubiquitous, invisible cryptography that began with the 1991 PGP controversy and the 2013 Snowden leaks. On a 100-year horizon, the step may be remembered less for technical novelty—algorithms will change—than for cementing the norm that personal communications, even on incumbent carrier channels, are nobody’s readable business. If the cycle repeats, today’s privacy victory could become tomorrow’s regulatory headache once metadata, AI moderation, or quantum decryption enter the frame.
