Apple’s developed a much more powerful ecosystem than any android device, and they used that power to control the mobile carriers (from China to France to India and even Brazil). This had nothing to do with teens in the US - they wanted power to demand the world wide carriers to do what they wanted and this was one of the ways they did it. It’s much more complicated than iMessage.
That’s why I’m skeptical that RCS will happen in the near future.
Sorry to burst your bubble friend, but a trillion dollar company is anything but “simple”
I’m sorry you’re upset about Apple being what they are, but while most of the world doesn’t have an iPhone, Apple commands the dominant share of the phone market by dollars, and by software. And like it or not, every mobile carrier in the WORLD has to cater to Apple when it comes to device requirements. So after 15 years of working directly with these companies, I can confidently say Apple and their chosen feature set does matter, even if you don’t like it.
