This is an extremely strange rewriting of history in which Google is some kind of altruist, moved by the plight of suffering school-children in a brief period where the rich bullying the poor (something truly shocking and unprecedented) over the color of their messages simply couldn't be tolerated any further.

RCS is not modern. E2EE is only an addon and it's not open. As others have mentioned it's not even available with interoperation. And it was really invented by carriers for exactly that purpose: To regain SMS/MMS revenue. But at this point here in Europe SMS usage between people had vanished anyway (except for spam and poor 2FA implementations)

And the social problems are not a technology problem, it's more a result of the harsh competitive American society. Without blue bubbles there'll be something else that kids will be bullied for. Only when the whole concept of "everyone except the #1 winner is a loser" is dropped this will disappear.

And Google didn't try to convince Apple to do this out of the goodness of their heart. Like I said most of the protocol (except the E2EE) is open but the implementation is not. It gives google even more control. You also won't be able to use it on a PC without a google account which is a big dealbreaker compared to Whatsapp and Signal. iMessage isn't a thing here in Europe anyway (neither is SMS/MMS).
