Doesn’t matter either way because everyone uses WhatsApp anyway.

RCS will never be able to compete with either because it’s a GSMA standard. Apple or Meta can think of a cool new feature, add it to their client and roll it out to all their users with the next update.

If they want to add a new feature to RCS, the GSMA (An organization with over 1500 members) will have to for a committee, they can then talk about their conflicting interestes for a few years before writing down a new version of the standard, then dozens of clients and servers at hundreds of different operators need to be upgraded before everyone can use the new feature. Due to this bullshit RCS will never be able to keep up.
