Earlier quoted context omitted.
I quite literally don't need to care about the blue bubble nonsense. It's a great flag for a person I can happily ignore.
I have a family, small children, relatives. Grandparents loves to see videos of their grandchildren. Sharing a video via group MMS is fraught with problems, it often doesn't work, or the resolution is garbage. iMessage works every time. I'm not dismissing your experience but the green vs blue bubbles do make a big difference for many of us.
The actual color of the messages really isn't the problem.
