I asked if people chose iPhone for the blue bubbles elsewhere a couple days ago, and while there was some good discourse on that post, the blue bubbles definitely also came up as a reason.
In my experience, when people find out my texts are green, they oftentimes would rather switch to a different platform altogether like Instagram or just not text at all.
Is this actually a deal-breaker in friendships out there?
I use them all the time as acknowledgment. Do you need a whole text knowing that I read the schedule for an outing later? Probably not. A Thumbs Up reply/tap is an easy way to communicate you read the message without needing to type a while unnecessary message.
