Yeah RCS always has been an embrace extend extinguish thing. The carriers were super pissed to lose their SMS revenue to WhatsApp and iMessage so they came up with this shit to be an active partner in the loop again, and they can bill for it again. Consumers didn't fall for that and it died off.
Unfortunately Google revived it but it's a very poor standard for interoperability. Not only because the lack of true E2EE in the open spec but also because you need to be a blessed party to run an RCS server and communicate with others. You can't run your own or choose a party you trust. It's either your carrier if they bother to run one, or Google.
It's just another power grab. Don't fall for its 'open' guise. They want you to use it so they can make you dependent and lock you in again. There's nothing open about it. If you want privacy, use signal. If you also want an open and federated network, use matrix or xmpp with OMEMO.

I strongly disagree with this negative characterization. RCS was a replacement protocol for the extremely outdated SMS and MMS protocols. Apple only supported SMS/MMS chat with Android users in iMessage, which meant that cross-platform chats were strongly limited in many ways (e.g. the mentioned emoji reacts), which caused many US American kids to be socially punished for having an Android phone, which is likely part of the reason why Apple is so dominant in the US now, especially among younger users. (Other countries mostly don't use iMessage/SMS, but something like WhatsApp, so they never had this problem.)
RCS was the solution to these iMessage/SMS/MMS incompatibilities. It took years for Google to convince Apple to adopt it, and Apple only announced doing so after EU regulations were on the horizon. There were even internal emails which revealed that Apple used their iMessage dominance and the poor Android compatibility via SMS/MMS to boost their market share in the US.
In summary, RCS is great because it is both a modern chat protocol, unlike SMS and MMS, and an open standard, unlike the closed iMessage and WhatsApp protocols, and available cross platform, unlike iMessage.
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.
Yeah what would really get me onboard with RCS if it were actually open, if I could choose which RCS provider I wanted to use. Like a privacy-driven foundation similar to Signal. Someone I could actually trust.
But that would mean that the entire protocol would have to be made open including E2EE, and that other parties besides Google and the telcos would be allowed to run servers. Those things are very unlikely to happen.
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).
iMessage isn't a thing in Europe?
No not really. It's technically available but nobody uses it. Everyone is on WhatsApp. Even companies. I never get messages from contacts on SMS either (so it's not going through fallback). I think it's because iOS just isn't really that widely used here. Not used enough to have critical mass for an iOS-only messaging service.
At least in the countries I deal with in Europe (Netherlands, Spain, France, Ireland). Perhaps in UK the adoption is higher because they have more money and thus iOS usage is higher. But everyone I know is on either WhatsApp or Telegram (and sometimes but very rarely Signal). Also we are much more socially disconnected from the UK since brexit.
As a bit of added info, the reason SMS is so hated here is because providers offered paid SMS services. You could sign up for e.g. daily weather reports and you got billed for it on your phone bill. It could be up to 1-2 euro per SMS. Some countries even up to 5 as far as I remember. This service was abused a LOT by scammers who just signed people up without consent and refused to remove them. The carriers did almost nothing against this because they were raking in the euros. This caused people to be very wary of SMS. Most people I know never use it anymore. They get worried when they receive something because they are afraid they'll get charged. Which can really add up if they do it from the start of your billing cycle. So its use as iMessage fallback is also pretty nonexistent.
So this is also why I am so wary of RCS and the carriers. They have played a deplorable role in the 2000s/early 2010s. Really cashing in hard with small bundles and insane out-of-bundle charges for SMS, the pay service scams etc. It was really their cash cow. So my trust in them is forever lost, I will never trust them to provide more than just transporting neutral bits from A to B.
It's also why I will never sign a contract with telcos and always use prepay. That way they can never take more of my money than I have in credit.
