Samsung has released a new video in support of Google’s #GetTheMessage campaign which calls for Apple to adopt RCS or “Rich Communication Services,” the cross-platform protocol pitched as a successor to SMS that adopts many of the features found in modern messaging apps… like Apple’s own iMessage.
AFAIK there is no open source messaging app that support RCS yet. It’s not even included in android AOSP (or is it? I can’t find any reference). It would help with adoption if google actually open-sourced the RCS client app.
They won’t let any third party apps use it so they are basically as bad as imessage.
The simple fact that iMessage has 0 interoperability makes it much worse than everything else.
So I doubt RCS could be as bad except if they remove the ability to operate with other RCS clients. And even for Google and Samsung that would be extremely stupid.
