IME there's a loss of a number of features when communicating without someone with "blue bubbles", that you come to take for granted, and that cause a bit of friction when you realize the messages/functionality you took for granted in your exchange aren't there. If I find myself chatting with someone with green bubbles, I find I tend to transition the conversation over to whatsapp.

It's not like a "relationship killer" or something, but I imagine it is a low-level contributor to my lock-in to the platform.
