RCS is a new green? If you’re referring to the existing SMS green, that was Apple’s original color for messaging. They adopted blue to represent the transition to iMessage. So you can’t say they picked a poor color on purpose; it was representing their own product originally before they even came up with iMessage.
Yeah, it wasn't always a bad green. They absolutely chose a bad color on purpose - arguably the world's best design company accidentally uses a painful high-saturation low-contrast background color that violates their own design guidelines for like 8 years by mistake? Give me a break.
Originally it was because iMessages were free, while SMS were $0.15-$0.20 each. So glad Apple broke that monopoly, along with many other anti-consumer wireless provider restrictions.
Did Apple really break that monopoly? WhatsApp was released 2009 with the explicit pitch that it was "free SMS". iMessage launched 2011, and with the anti-consumer Apple lock-in, and isn't even much used outside US.
Also free/unlimited SMS was prevalent in many countries before WhatsApp or iMessage. And there were plenty of IMs before that too.
