Whenever this issue of iMessage crops up on HN, I’ve come to expect the usual points from both sides. However, the one thing that’s never addressed is the “why” of it all. For a group that ostensibly values openness and interoperability, why spend so much effort and energy to climb into a walled garden?
Because half our friends/family/etc own an iPhone and they either use iMessage or WhatsApp, and neither is acceptable for the likes of me. And since they don't 'stoop' to the level of Signal, we can 'stoop' to the level of iMessage (but definitely not WhatsApp).
Blue-bubble envy is real. I myself am a green-bubbler but every once in awhile I feel this tinge of "otherness" when I see "Loved an image" in the group chat.
