It’s not just the color of the bubble. On iOS, green is a warning that at least two things are true: 1) The other side is subject to blanket surveillance (which is probably true of RCS, assuming Google implemented the client/backup). 2) The other endpoint cannot handle images or videos correctly. Based on their track record with the last dozen communications platforms Google has built, this is probably also true for Android RCS implementations. For example, the other day, someone attempted to use gmail to send me a locally stored image, and instead it sent a URL back to some server somewhere. This is neither SMTP nor SMS’s fault. Presumably Google’s RCS client will eventually pull crap like that too. Hell, they try to do it with HTML (remember AMP)? Note that, following this convention, Signal messages are correctly colored blue, even when sent to android. (I know that apple does not dictate these colors. Just explaining what “green bubble” means to people that are used to android’s bullshit.)
