I predict one of two outcomes once Apple becomes aware of this. Either they’ll modify the iMessage protocol to break Nothing Phones compatibility, or they’ll sue Nothing Phone for violating some kind of IP law. Apple absolutely wants to maintain their walled garden and letting a non-Apple product transparently interact on equal footing with Apple products runs counter to that.

The messaging is provided by a third party who is dedicated to working on their iMessage compatibility. Apple has no reason to stop this because this is a good move for them in the larger battle between mobile messaging standards.

Google owns Jibe, the company behind RCS messaging found on all Android phones and an emerging, competent product from the only game in town that can compete with Apple. Google has decided to take this to the government level and push for a unified phone messaging standard, normally a good thing, but people their own RCS solution.

Apple is pushing iMessage as a protest against Google and their inevitable lawsuit to conform with RCS adoption. Android may win unless Apple shows it has parity and provides a non-legislative option: if enough people use iMessage then governments don’t have to make any laws or enforce changes. The company Nothing is using iMessage, which helps Apple prove there is both a significant user base, which would cause a burden on Apple and it’s customers to change, and there is no monopoly on iMessage or messaging in general. So if enough people use iMessage, Apple sees it as a good thing.

RCS is not a Google product, see en.m.wikipedia.org/wiki/GSMA

Apple has been pushing iMessage for quite some time, but they want to keep it just to their platform and have made no attempt to make it open to other users. That’s Apples way and it’s not as a “protest” to Google lol

That’s like saying they made the lightning port as a protest to USB standards, nah they just want their proprietary shit.
