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.
In theory anyone can host an RCS endpoint but in practice that means carriers (historically) or OS vendors (in modernity). So in effect yes all RCS messages will pass through Google servers, but mostly because Apple to Apple texts will remain on iMessage. But any texts starting or ending on Android will go through Google. Note that this doesn’t really change much as Google’s privacy policy for Android users already discloses the bulk ingestion, scanning and processing of communications, including text messages.
I thought that it was the carriers the ones hosting the RCS server. Is this not true?
Some do, but what Google rolled out in Android Messages is their own implementation unrelated to the carriers. Ostensibly so it works regardless of carrier, but what they rolled out is a semi-proprietary implementation that only works on their app. Ergo if you use a third party texting app, no RCS. So it’s a sort of “Android iMsssage” thing anyway. Apple plans to implement Google’s version, again sidestepping the carriers.
