I was responding specifically to @Stapy 's account of their family, but also informed by the first few times I heard about green bubbles (or about iMessage in the first place).
As I said, it really isn’t a thing in Europe. If I don’t count my brother’s work phone, I know, I think, two of my friends and a handful of my (invariably older and richer) work colleagues who have iPhones, but if I had to guess less than 5% of my phone contacts use them. So when I first even heard about green bubbles was when (American GenX and Millennial) people on a podcast complained about green bubbles from their friends. I was taken aback. From context I could gather that it was an iPhone/Android compatibility thing, but they sounded like the most horrible classists and not at all self-aware about what they were doing. Just genuinely disgusted that their friend would show up green. It really made a big impression on me because I knew these people to be otherwise liberal open minded people.
I have since heard that attitude several times from different podcasters but never in real life (I communicate with my American friends via Discord or, increasingly less so, over Facebook Messenger).
So this isn’t entirely based on media scaremongering, more on unselfaware first-person reporting. The WSJ article (which is open for me?) just reinforced these attitudes I had independently observed and frames them as a youth thing:
Grace Fang, 20-years-old, said she too saw such social dynamics among her peers at Wellesley College in Massachusetts. “I’ve had people with Androids apologize that they have Androids and don’t have iMessage,” she said. “I don’t know if it’s Apple propaganda or just like a tribal in-group versus out-group thing going on, but people don’t seem to like green text bubbles that much and seem to have this visceral negative reaction to it.” Ms. Fang added that she finds the hubbub silly and that she prefers to avoid texting all together.
She uses exactly the right language here: what took me aback that first time I heard about it was that their reaction was noticeably visceral. As you can tell, it really made a deep impression on me.
Jocelyn Maher, a 24-year-old master’s student in upstate New York, said her friends and younger sister have mocked her for exchanging texts with potential paramours using Android phones. “I was like, ‘Oh my gosh, his texts are green,’ and my sister literally went, 'Ew that’s gross,’” Ms. Maher said.
She noted that she once successfully persuaded a boyfriend to switch to an iPhone after some gentle badgering. Their relationship didn’t last.
