So folks w/o carrier service can't share pictures? I can use iMessage on multiple devices w/o carrier service, works great.
Other than pictures and videos I'm not sure what problems RCS solves for end users, which is a big deal I concur. Its not encryption as that is not built into the standard and is app implementation specific.
Though I would find it funny to see Apple build an RCS implementation to sit under iMessage as a point to route around Google owning RCS.
But this is a convenience, not a necessity, as that twitter thread is arguing.
Yeah, through my carrier service and Google's implementation of RCS, I can also access most of my phone's features through the My Phone app on Windows or a web browser. Yes, my carrier service is involved in that, but that's not a problem because I have carrier service, as do millions of other Americans. And those who don't, but for some reason want to be able to send pics and videos to phones, have access to other services to do so.
RCS isn't a perfect solution, but in many ways neither is iMessage. But that's not a strong argument for Apple not adopting what is increasingly becoming the modern global standard for texting, and keeping the texting experience between iOS and Android logged somewhere between ICQ and Aim.
