Back in my online dating days, I did genuinely (more than once!) have women say "ew no thank you" when I texted them and a green bubble popped up on their screen. It's something that even non-tech people will notice and care about, so I'm not surprised to hear that it's causing stress for teens. I'd love to see the broader tech industry coalesce on a modern messaging standard that's device and carrier agnostic, but I'm not holding my breath, especially given Google's history.
