Explanation: The proprietary encryption of RCS is crap and is
undermining the security philosophy of iPhones.
 
RCS does not have a "raison d'être".

It has - it is the evolution of SMS/MMS as a common standard an not a
proprietary protocol like iMessage, Telegram, Signal, WhatsApp etc..

The implementation of a working encryption as part of the standard is
just a question of time:

"Today, we are celebrating a significant milestone in the evolution of
messaging with the launch of Rich Communication Services (RCS) support
on iPhone with the release of iOS 18. This launch is the culmination of
years of collaboration across mobile operators, device manufacturers,
and technology providers. It represents a step forward in bringing RCS’s
feature-rich messaging to more users across both iOS and Android.

[...]

While this is a major milestone, it is just the beginning. The next
major milestone is for the RCS Universal Profile to add important user
protections such as interoperable end-to-end encryption. This will be
the first deployment of standardized, interoperable messaging encryption
between different computing platforms, addressing significant technical
challenges such as key federation and cryptographically-enforced group
membership. Additionally, users will benefit from stronger protections
from scam, fraud, and other security threats."
