My "normal" friends and family are majority iPhone users. I'm Android.
I "literally ruin" their group texts. I've seen people actually reject relationships because they don't date people with "green bubbles".
Don't even get me started about work group texts.
I know restaurants where some of the servers have group iMessage chats with customers for early notification about nightly specials, Android users literally can't be added.
Likely not maliciously, but this has created almost a "second/lower class" of phone users that encompasses ~50% of the country.
