In a surprising move, Apple has announced today that it will adopt the RCS (Rich Communication Services) messaging standard. The feature will launch via a software update “later next year” and bring a wide range of iMessage-style features to messaging between iPhone and Android users.
Apple’s decision comes amid pressure from regulators and competitors like Google and Samsung. It also comes as RCS has continued to develop and become a more mature platform than it once was.
Do you have a link to those standards? All I could find was a high-level overview of “this is how the Signal based crypto is used in Messages” from a year and a half ago. It mentions extending the XML scheme used in RCS, but doesn’t provide a schema or any other details.
Google Messages and WhatsApp are both based on documented, secure protocols, and neither can be particularly trusted because both are run by data-hungry ad companies. I trust both companies to make the right choice in giving customers this little bit of privacy so they don’t leave the platform entirely, but they’re both equally iffy.
Hopefully with MIMI we will see complete cross-messenger compatibility, so open source messengers can be used for all communication.
Here are the links to the documentation for these standards:

I knew where to find these, but where are the details on Google’s implementation of them? Because that’s what’s most important here.
