Marginalising people for green bubbles is not something Apple can fix, that’s just shitty people being shitty to people.

RCS does solve the real-world problem of “sending images larger than 1MB” and “sending videos larger than 3MB”. It also fixes the god-awful group messaging standards, adds a whole range of modern texting abilities, and practically removes the character limit. That’s objectively better than how things are right now.

The RCS payment standard requires blocking rooted or jailbroken phones. Implementing payments (and I don’t know if they already do) and permitting rooted phones would actually violate the standard. If Google makes it so you can send people money through RCS the same way you can with iMessage, they have a very good reason to ban these devices, even if I may personally disagree with it.

I don’t text so I don’t give a fuck about what colour my bubble will be. It would be nice for Google to open their encryption system to the GSMA so E2EE RCS would actually be a possibility, but even without E2EE RCS would allow me to group text again (MMS has been disabled by most carriers here, SMS doesn’t support groups).

As for your Youtube app: you can disable it with ADB without root. There are good reasons for rooting your phone, but just removing Youtube is not one of them. If you did root your phone, you can turn RCS back on with the standard Magisk hiding procedures; once you get Google Wallet to work again, Google Messages should work fine, too.
