The reason Google loves RCS is because they spectacularly failed 4 or 5 times at introducing their own iMessage competitors.
Competing companies often act in their best interests. And both Google and Apple offer OS’s which have very different value systems. I think that’s good for consumers. If I want open (and all the pros and cons that come with that) I can buy an Android phone. If I want closed (and the pros and cons that come with that) I can buy Apple. If they Apple starts to open up a bit and Google locks things down a bit we get the worst of both worlds and no true options.
this is definitely an apple culture thing though. it's such a clear product choice to get apple users to pressure their friends into buying apple products.
Plus iMessage doesn't allow you to send RCS messages from your laptop, whereas it's easy to do that with Google messages. That makes people with iPhones think RCS is worse than it really is. It's just iMessage that's intentionally hobbled. Not to mention the hostile UI decisions made by Apple, which seems to be the main knock against anything non-blue.
It used to be black text on green: https://mobiforge.com/files/iphone-sms-1.jpg
The white-on-acid-green color combination would not make it through any accessibility review. It's literally impossible for a lot of color-impaired people to see, and objectively unpleasant otherwise.
Apple gets plenty of complaints about it. Just look at the Apple forums. Their literal advice to fix it is "make your friends buy an iPhone".
What form of color blindness doesn't let people differentiate between levels of brightness? I checked a couple color blindness simulators and it appears legible.
Heck, white on light green appears to be used in articles about good design for color blind accessibility without any indication that it there's anything wrong with it.
