Fair enough, agreed that social groups dominate the dynamic more-so (e.g. any country other than US). But being the default, pre-installed, and only app with SMS integration on iOS is an unfair position to compete from, especially when iOS is now slowly gaining dominant market position in the US.
It's not really how it works for a lot of users in the US. As I get it with the more social demographics, most use different apps for messaging for different contexts. social media like twitter or instagram for more public casual chatting with strangers, maybe private messages on said apps for growing relationships, then for more personal stuff some mutual messenger app.
social demographics just use the chat that is closest to whatever they like to do online. iMessage is more of a "it's always there if I need it" thing as I get it, not so much something chosen out of confusion -- the social demographic is quite good at compartmentalizing their lives across many apps.
