As far as I've read so far Apple is adding RCS support to the Messages app, aka alongside SMS & MMS: https://www.theverge.com/2023/11/16/23964171/apple-iphone-rc...

It's not clear if iMessage will interoperate via RCS, which is what would make blue/green bubbles less relevant. My assumption would be no as they'd cede moat, and there isn't much of a network effect for them to gain from.

Apple is not changing anything about how iMessage works, it's clear in their statement in the article you linked:

> We believe RCS Universal Profile will offer a better interoperability experience when compared to SMS or MMS. This will work alongside iMessage, which will continue to be the best and most secure messaging experience for Apple users.
