I agree with your point but imo the drama doesn't even just come from high school kids. I'm a year away from graduating undergrad and still wondering when (or if) people are going to grow up about it. Even then, full grown adults do it about as often as people my age in my experience. Honestly some of the worst offenders when it comes to green bubble shaming have been my family members on the older side who think everyone should just get an iPhone and refuse to use anything other than iMessage.
