I don't care if anyone has a Xiaomi, Oneplus, Samsung, etc. Each brand is using a modified version of Android, and they chose to be compatible with each other. But for example the "blue vs green bubble" drama is a thing specifically because of Apple locking their unsuspecting users into a closed ecosystem. And it sure isn't Android's fault for not being compatible with it.
The more power a company like this gains, the worse will it be for the whole industry.
You're probably an adult, the whole blue/green bubble is targeted at high school student demographics, ya know, the same demographic who LOVES pointless drama and bullying over stupid shit like the color of a text bubble
Apple likes this setup because by the time you leave HS you'll probably have switched to iPhone due to peer pressure and are unlikely to switch later because "it's just what I've always used" and like you've noted no longer care about the blue/green bubble debate
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.
