I mean all of this is shorthand for people being mad that they lose all their chat features. Its never been about the color of the bubbles but what the color of the bubble represents. If the bubble turns green now you don’t have delivered or read receipts, no typing indicators, no high quality media, can’t add or remove people from the chat, the chat is no longer instant, etc. So it may be juvenile to care about the color of the bubble but it absolutely makes sense that no one wants to have less features while texting
